Ahhh...I got it now.
If you can get an 80mmTB kit INSTALLED for 2k or less,you better do it fast.
I dont think you understand the work involved with doing one of these installs still.I'll sit back,drink beer and watch while you install yours...

We were almost discussing an off topic thing. I understand that the 80mm kits sold by tuners are costly. I also understand that no matter what kit you use, the labor is the same. MB Service gives the techs 5 hours to swap out a TB (plenum and all). I've spoken to 2 techs that both have done RennTech installs and they said it took them 3 - 5 hours. Even at a $100 bucks an hour, we are looking at a minimum cost of $500 (regardless of the kit).
Now, the deal becomes getting the parts. If I can walk into my dealership and buy the 4 parts for a total of $1200, then why can't everyone else?
$1200 + $500 = $1700 COST. So, I agree that Jrocket wouldn't do it for under $2000 because there is little profit in it. BUT, for those of us that want 80mm TBs (and I am a huge believer in it for this car) this is an option.
It is no different than the cooling upgrades. You can buy a kit that has all the parts or you can get a new HE and pump and do your own plumbing.

Just to help, (Torque X RPM)/5252=Horsepower
So at any given RPM, more torque will net more horsepower.
Torque is one component of Horsepower.
Here is a link that explains quite well.

Air fuel is too rich higher up - seems like ECU was dumping fuel as IAT's got too hot.
Pretty dangerous if you ask me tuning a car on a dyno that does not give sufficient cooling ... also if you then you lean it out too much on there and whammo.
Reckon there are more gains available if you get the a/f better up top.
With a 178mm pulley I would say a larger cooling package is mandatory.

I am doing a cooling upgrade. I wonder if you only saw the gains due to the heat soaked in the dyno run? Were there actual gains? Going rich up top (which is what it does) wouldn't be from added boost. It would be from heat (as you eluded). i just wanted to clarify for the viewers. Assuming I have an adequate cooling system, do you really see gains in an ECU tune? If so, I'd like to see the numbers and know the brand. I have stayed away from it because I see cars that have ASP pulleys walk cars that have ASP pulleys + ECU tunes. Not just one or two either. I've seen the same with Renntech setups.

Hi adam I'm new to this site and just picked up an 05 E55, looking to do some engine mods with tuning but live in the Chicagoland area, can you recommend anyone for me? Thanks C.

Interesting. Is there something different in the ECU for the 06's?? Or just 03"+ in general?? I have a 05' and am looking into ECU tuning after the ASP thats why I asked.

The most notable feeling was immediate and fatter torque throughout the rev range. The ASP on its own was a little binary ... when you wacked it, the car seemd to take a berath and then would go ... but even then it did not feel nearly as quick as it does now. Its frustrating as I would like to know what numbers I am putting down but getting a dyno here in UK is like trying to find Paris Hilton's modesty.

You need to have your car checked out..
You are either running too aggressive a timing map and the ECU is dumping fuel on you, or you have belt slip.
How many miles on your car? You might want to spend $35 and go and get a brand new belt and redo your dyno and see if the problem goes away.

Dyno #1 was a baseline dyno. Dyno #3 was after the mods. Dyno #5 was with mods but with further ECU fine tuning. Temps in the Bay Area were in the low to mid 80s during the 5th dyno. Temps were in the low 90s during the 3rd dyno. I think the dyno were run in 4th gear.
Adam (through the magic of Oliver) will be doing more fine tuning on the ECU to eek out more HP.
I do have a couple of questions:
On the 5th dyno, the HP increased by 25 RWHP but the RWTQ by only 3 lbs??? What's up with that?
How much of a difference will the 10 degrees of temps affect the stats?
Also, I noticed that air flow (read small fans to cool/feed intakes) probably did not help. I was expecting more gains with these mods.
What do you all think?

What we didn't posted is the car was suffering from tremendous heat soak. The next run after number 5 was a loss of 25 hp.
