Another Jerry/LET tune! Joining the 12s club
 

Yes, I finally got my Christmas present :rolf:. The Jerry’s tune finally arrived. Shipped it out Monday and got it back Wednesday eve. I installed it and took it for a drive. I did not feel any big different (hunger for power) but the wheels span all the time :rolf::rolf::rolf:. I knew my gut dyno couldn’t tell anything:crazy: so I took out my G-Tech, ran to the empty street that I used to test when having new mods, but damn… it somehows wasn’t that empty last night:nix:. I could only manage to do 1 1/4 run and 2 0-60mph runs. I screwed all my runs since so much wheel spins. All 0-60 are 4.7-4.9s/12.9s while I had 4.6s/13.14s before the tune :rolf::rolf::rolf:

The ¼ mile run (the only 1 run with all wheel spins to the 2 gear) was
2.237s 60ft :eek:
4.7s 0-60mph :eek:
8.59s 1/8mi @89.71mph :naughty:
12.91s:eek: 1/4mi @ 114.22mph :naughty: (is this the same trap speed with stock E55?)

This was at see level, street tire normal pressure, 45F
Code3 pulley + Intake + Filter
Modified intake manifold
LET tune

All the three runs were showing very much same power. Compare to the best run before the tune, the peak gain was 40 whp/ 48 wtrq. It was 30+ whp and 40+ wtrq gains all the curve.:y

Man, this gain is really sucked for the wheel spin. I have to re-learn to launch the beast now. I do believe I could manage this beast to very mid-low 12s/117-118mph:naughty:. Keep you an update if I can.

Thank you Jerry/LET.:y

PS: this info is based on G-Tech data. I just want to share what I have. Please do not quote. I am looking for more power:zoom:

Nice! I already paid for my tune but havent had time to send it in but this monday im gonna try to over night it!

wow nice gains and nice trap speed! what have you modified with the intake manifold?

:yWelcome to the JerryTune world:y

Now take it to the track:naughty:


I will say its very hard to hit 113-118 mph even heavily modded:zoom:

But hey maybe you can be the first:y

Thank guys for all nice words :)

I had it customed based on 240SRT's spec. Credit for 240SRT. Without tune I did not see that much gain on it. Credit for Jerry.

Thanks, but I don't have access to a track here. I would love to try but really don't hope to be the first one lol. However, it looks very promissing. Compare my mods to many ones here. I only missed the NOS:rolf:. Since I don't go to track, the heat spacer, IC pump, heat exchange etc are not important to me. Nice to have, always want to have, but only have those when I have extra cash hanging around :)

The point of this thread is I just want to say I do see gains :)

Thanks again guys!

great numbers...i just got a powerchip tune..so i'm hoping to dyno it soon to see where i am on the power scale.

Nice gains, CLKCLK. While the G-tech results are a small step up from "butt-dyno," it is better than nothing, and does appear that you picked up some power :y

What is your mod list at this point? I'm not familar with a CLK32M :nix:

i believe it's a CLK32 AMG:nix:

Did they offer those with a manual tranny? Maybe "M" = Manual?:nix:

Don't laugh too early :)

CLK32M: No it's not CLK32 AMG. Have I ever said it AMG? It still bagde CLK 320. Custome Procharger 9psi, 3.27 rear differentials and more.

C32: I fixed my sig. So hope to clear out the question about C32.

03 Vette: occasionally drive since it belongs to aunti now lol.

You are also in the bay, we'll meet one day on the road :D.

What did the "M" stand for? Just curious...

M = Modified:D

did you get a baseline prior to the Powerchip tune?
What mods did you have if any before and after the tune?

It is recommended you do the tune last after adding any mods.
Otherwise, you'd need to reflash after each additional mods and could cost money unless money is no object.:zoom:

right now i dynoed around 275whp..but that was was with the traction control on..stock...with a dying intercooler pump.

I have a code3 pulley and code3 intake. I just got the tune a week ago.

Pshek said he was running lean after the powerchip tune so i want to dyno it just to make sure my af ratios are ok and how much power i'm making.

Thanks for the tips.

These are my numbers on a Mustang Dyno.
Last tune was with a C3 pulley, C3 intake, and a PowerChip retune. I think the AF is on the safe side.

nice! so would that be closer to 310-322whp on a dynojet?

Thanks, but, I think the numbers are still conservative. The last tune (with C3 intake) indicated i lost some torque actually.
Travis (PowerChip) is looking into it.

BTW
Stock RWHP is 273-275 range
My reading is 281 RWHP despite all the mods. :nix:
Top speed reached 165 MPH for now.:zoom:

only 6-8 rwhp with all your parts?

something has to be wrong:nix:

i believe 275-290rwhp stock is on the dynojet not a mustang dyno.

my air/fuel's in the 12's. from the graph you posted it looks like it's in the 11's if I didn't read it run. too lean maybe?

I'm very inclined to agree with you.

That's what Vadim said.
I'm missing at least 20 RWHP.
:nix:
It's really frustrating to see these numbers. I guess I need to take it to the tracks and find out 'cuz I do feel the car is faster.:X

Yeah , maybe its the tune?. :nix:

Those stock numbers are what most usually get on a Dynojet, NOT a mustang (aka heartbreaker). Even on a mustang your 281 seems a bit low for what you have done. I would expect something closer to 290whp or more. Most get 310whp or more on a dynojet with your same mods.

yeah i read that a mustang dyno reads around 11-15% lower then a dynojet.
