I have been researching mods for over two years at this point. I have had my car for over a year and because it was new to me, I left it stock while doing preventive maintenance. Glad I did so because I needed a lot of little things done to make the car to make it whole, like Transmission Oil Pump and IC water pump, motor mounts, tranny mount, spark plugs wires and ect.
After making my car whole and making sure I did not need anything else to start modifying it, I started data logging IATs to see what stock parameters looked like and see how fast the recovery ways on a stock set up with a new Bosch 010 IC pump. Normal Driving I would see a range of about 14 to 25 degrees over ambient. I got an average of 19.5mpg over 20K miles. (not bad)

(I use the Torque App for IPhone with a cheap WiFi module that plugs into the OBDII port) (5 bucks for app and 12 bucks for module on ebay) Android uses a Bluetooth module (FYI)

So I took the plunge and ordered a FSP 77mm + Tune because I did not want to replace the crank pulley and was scared off by the clutched pulley blowing apart under load. Honestly really glad I did, and really glad I went with Eurocharged. Install was cake took me no more than 1 hour including cleaning under the hood. What floored me was the plug in flash from my laptop. It was super simple to down load the stock file and send it to Eurocharged for a tune. Upload was as simple as well, I did hook my battery up to a charger as per the suggestions in the directions and really recommend doing that while flashing.

First drive, I can really feel the imitate torque at very low throttle inputs. The best way I can describe it, feels like the car lost 700-1000lbs at low speeds or initial start off from not. When hitting the throttle hard while in manual Sport mode it puts you into the seat hard and keeps you pinned all the way to redline. Its performance is addicting and I’m amazed I did not have a run in with the law yet. I never thought the car had lag until I installed the FSP. Power is instant, smooth, and objects in the review view mirror are gone very quickly. Honestly I think my car is fast enough and makes more than enough power now. That being said I will be adding a HE for good measure and long tube headers when I have some extra coin burning a hole in my pocket.
I have one very minor issue with the resistor I got with my Pulley. It was bad one, giving me drivability issues like bucking and hesitations I have removed it and it runs supper smooth now slight hiccup at about 1.2-2K rpm. I ordered new ones and will report back after the installation.

IAT’s on hard pulls from 40 to 145mph I have never seen over 155f and recovery with the stock HE is about 30sec or less and about 5min cursing to normal cursing temp +25-45f. I’m seeing 25-45F over ambient cursing at all different speeds. As far as MPG, well I’ve really been nailing it so they suck but I did drive home nicely last night and averaged about 19 and change at 75-80 mph.

Big thank you to Jerry at Eurocharged. He was just wonderful to deal with. I could only do the install during the weekend because of work and person life. I sent him my stock file late Saturday night and he had my tuned file back to me in less than 24 hours on a Sunday! Also he worked with me throughout the Thanksgiving Holiday to resolve my resistor issues. Thank you Jerry for all your help and making my car fast as hell.

My Best and again thank you to all the board members for helping me thought my questions and getting my car to run tip top!!

EDIT: Update: I just revised my 50 pack of resistors from Ebay and installed last night. All bucking/hiccups/surges are gone!!

I bought my car with the 83mm pulley from EC and I'm fine then again I don't best my car often

MTV10

Nice!
my 80mm FSP goes in tomorrow... pretty excited.

Quick question: What module are you using for the Torque app with iPhone?
Do you have a link for Ebay?
I'd like to invest in something like this for peace of mind.


Edit: I'm planning on running with no resistor. Most people have said in their reviews that the car runs smoother without it, even if the tune states that it is required.

CharlyE500

Very useful review

MTV10

BTW... what is the slight hiccup like at 1.2k-2k RPM?

Glad you like the FSP

We have 72mm and 74mm ones now too

FLE55AMG

Damn dude, your like a crack dealer Need HE I'll be coming to you for the PLM one once the holidays are over!

FLE55AMG

Like power is killed for a millisecond and then back on Not under heavy load. Maybe ECU sees boost and adjust maps or somthing.

FLE55AMG

This is the one.

The Eurocharged Software has data logging it it. But it's a pain to drive around with a lap top open also I don't know how the cops will take it when I get popped.

Running with our resistor? well my car feels great without it. I'm paranoid of a lean condition. But in closed loop cruising and I'm assuming don't know it as a fact but the front 02s are adjusting the fuel curve for best MPG and that 14.7 to 1.

Lean condition is not the end of the world but transition from closed loop to Open loop under 100 TPS 100% load could yield a knock event because boost is there but fuel and timing are not addressed to handle it? So what would happend ECU pulls timing and maybe fuel is dumped and you lost performance and got knock?

MTV10

Yes I think that's exactly what's happening.
Probably switching to the 'Supercharger ON' map.. even though it is always ON.

It was very good of you to complete all the maint before installing the mods, your car is running much healthier now with the new mods because of it, next mods for you should include headers and heat exchanger I originally had my car set up similar to you with 83mm pulley and tune then I drove a 55 with the mods I spoke about and man what a difference by far the best mods ice done so far

ghlainez

FLEE55AMG does that resistor need to be plugged in for the fixed pulley? mine is plugged straight in to the harness per Tony. had a few tunes but still having fuel issues, either to lean or to rich. bucking and surging at low rpm's.

FLE55AMG

I could not agree with you more. Getting the HE after the Holidays and MBH headers sometime next year. Doing colder plugs in a few weeks for good measure.

FLE55AMG

Did you try different resistors? Jerry had me switch it around and even take it off to see if it made a difference. I ended up going to ebay and buying 50 of them for 5 bucks and used the ebay one with NO issues.

PM your addy I'll mail you one to test to see if it fixes your issues

yes mine is plugged into the harness I'll take a picture and post it.

ghlainez

Mine has no resistor at all. Tony's tune didn't require a resistor. It ran great with no issues till I put 82mm TB and injectors and that's when the problems started.

FLE55AMG

So it's the TB that is the issue. Every tuner is having a hard time getting these cars tuned right with the upgraded TB. Might need to go clutched pulley instead and get it tuned with the TB. Or remove your TB get a 74mm pulley and tune with those larger injectors.

MTV10

Do you find your car pulls harder with or without the resistor?

FLINTY55

Not in disagreement but why would a larger TBody do this. TPS sensor reading voltage differently on the larger TB? I don't pretend to know how the factory computer handles a tune but coming from the Mustang world, 90mm TB's seem to do fine without a tune as a bolt on. Apples to Oranges I suppose but still...???

Ls1toAMG

It's happened most times. It hasn't been explained why/ it's unknown. IMO it's a side affect.

FLINTY55

Is this from the injectors added to the mix or a common occurrence with the larger TB sans injectors on other E55's? Reason I ask is to do a little digging with my tuner on this matter.

Ls1toAMG

When people go back to an 80tb they don't have any issues.

FLE55AMG

I don't know enough to agree or disagree with you? I think since a few tuners have had some success with the larger TB, the problem could stem from the required STAR SYSTEM configuration need to be done after the install of TB. Mustangs are MAF or MAS based? These cars are MAP that would be one major difference if that's the case. Also the car was not designed and programmed to see boost until 2k.

FLE55AMG

Not harder just a way smoother transition from lower then 2K to over 2K. Feels more ready for boost with no delay. Feels like it's not searching for a map like before.

ghlainez

so is it the larger injectors that's causing this issue?
