Stay far FAR away from PES TUNING!!
When I got it back, I was very disappointed. The car felt slower then when it left, and it sounded like crap...like I had a bad exhaust leak. I blamed the slow feeling on the fact that I had been driving my M3 for the past few weeks.
, and after having the car on the lift and not finding anything, I blamed the exhaust leak on the sound of the Kleemanns coupled with the catless straight back exhaust. I ran the car at MIR mid April, and the car ran an 11.54 but still didn't feel like the power was there. I think my best trap was 122mph. I datalogged all my runs, and ended up sending them out to a few experts on the board for their thoughts. Upon review, it turned out that my PES tune was running hardly any timing and my afrs were all over the board. It was like someone who didn't know what the they were doing or better yet didn't care about what they were doing had tuned the car. So, after spending what was a large sum of money with PES tuning, it was back to square one.
Now we get to the good part. I had the car tuned a few weeks back by a reputable company, and the car picked up 80whp and 95ft lbs. (side note, there was another PES tuned car at this tune day and he picked up more then I did!!) I have datalogged this new tune pretty extensively, and my afrs are actually a tad rich and the timing looks to be perfect. So, PES tuning aka POS tuning not only tuned my car with unsafe AFRs, but also left 80whp on the table. But wait, there is more. The sound of my exhaust sucked. It really did. I figured installing an x-pipe would definitely help. I had a local custom exhaust shop do the work, and when I picked the car up, they asked about my exhaust leak. I explained that it didn't have a leak that we could find, it was just the sound of that set-up. They kindly informed me that oh no, it has an exhaust leak. POS tuning had installed my Kleemann headers with absolutely NO GASKETS!!
That my friends was the icing on the cake. So, anybody thinking about using PES or have friends thinking about using PES, I implore you to share this information.

As we've seen many times in the past, a wrong tune coupled with an aggressive setup could cost you an engine. It's not worth the hassle of saving a few bucks and going with unknowns yet people do it all the time.
Imagine if you popped a piston out of it OR WORSE!!
When I checked my tune, I almost had a heart attack. Timing was out of control!!! It was a ticking time bomb.
So glad I got the mighty tune on from the secretive "greatest tuner on the planet". Cough...jeremy...cough cough
What do you think she'll trap now?
Have you gotten the IAT's to settle down some?
Love how your car is turnin out mang!

LOL.All joking aside sorry about your nightmare story im glad things worked out for you. SO with the 80 more horses you picked up how much power are u putting down now if you dont mind me asking?

Clayton, yup, no gaskets. I was never going to make this thread. Figured the tune was just an expensive learning mistake...$1500 for a joke of a box tune!
But no gaskets on the headers pushed me over the edge.
Haha..glad you guys had a blast!! Wish I could have made it.

It really isn't that big of a deal when it comes right down to it, but just don't want others to make the same mistake. Imagine if you popped a piston out of it OR WORSE!!

Just over 500whp




Thanks for sharing and I'm glad you got it all sorted out. Hopefully you'll save others from making the same costly mistake.
Headers with no gaskets, what a cheesehead.

Just thought I'd throw in some perspective with this number - I dynoed 370whp on the same dyno on the same day (totally stock except for the CF intake tubes and K&N's).

No gaskets, unfnbelievable...we should burn that place down.
BTW how does it sound now? You still unhappy with the exhaust note?

930chas, thanks again for posting

It sounds really really good now!!



I do want to say that Patrick from PES has been in contact with me to apologize and to see what can be done to remedy the situation. I haven't dealt with him before, but he seems to be a stand up guy. He also feels that my headers do have gaskets. I don't, but I will be pulling these headers in 4 weeks or so, and will report back with what I find.

Also, your car is fierce now with the new tune. MIR will be inundated with black e55s this racing season!!
Why don't you go out there and get that 60-130 time like we were talking about.
Two, this is why this needs to be an open forum-STOP WITH THE SECRETS and backdoor agreements people. Spill the beans, others will only suffer.
Care to share who did your tune this time around?
Thanks for sharing.
