Dyno numbers..is this right?
Had my ecu tuned and here are my results. Obviously, the numbers are lower than stock let alone a car with a tune. I also ran the 1/4 mile after the tune and ran 12.78 @ 111.28 with a 2.073 60ft time. Not sure what gives..does this sound right?? Thoughts?
Here are some facts:
Track-
07 Cls 63
20 HRE's
80 degree outside
90 degree oil temps
Ecu tune only
Dyno-
Mid 80s outside
90s oil temp
Traction off
Manual mode

Don't want to turn this in to a tuner bashing discussion so won't say for now. I didn't dyno the car pre tune so I don't know if if can say its part of the problem. But I definitely thought I would see better numbers. That's why I posted the dyno in hopes maybe someone could see a prob the a/f ratios or whatever..I'm no expert and don't know what I'd be looking for. Monday I emailed the company the dyno files to gain their thoughts but haven't heard from them yet.
My trap speed at the track suggests my car is putting out 490 ish at the flywheel which is prob about where my car dyno'd factoring in drivetrain loss. I think I could have better at the track but don't know that I would do good enough to hit the hp I would think the car should put out.
It's bugging me.

I did dyno the car on 2 different dynos..the first time I sent my ecu there was a problem discovered when I dyno'd it the first time..the speed limiter was still set at 155 and was getting slightly lower hp numbers than what I posted in this thread..sent my ecu back and dyno at a different place.. Don't think it's the dyno..
Does dyno mode make a big difference over manual?

Looking at the numbers it would seem that way. The only indicator that part of the tune was successful is the speed limiter. It passed the 155 mark and hit 190 on the dyno.
They still haven't responded to the dyno file I emailed them Monday and that's starting to **** me off. They were super responsive pre tune and when I had to send my ecu back a second time they were responsive...I guess they are done with me.
I'm just looking for their thoughts. I'm going to call them...was hoping I would be able to write a nice review for the but haven't had that type of experience. Although a review may be coming...
