Update: 3/6/12


I went back to PRS and tried to get some issues smoothed out. I am still having random missfires. Even on back to back runs without changing anything. One run the car will be great, and we do another pull and it will break up. Even at 28 psi it breaks up.

Mike got me a super nice and smooth graph and boost plot (that I will try to get up later) with smoothing at 1 of 99 and you would think it was set to75 or so. Then we took it on the street and it started breaking up sooner than I had experienced it before, around 5800rpm.

We put brand new spark plugs in after I arived, they swapped out the coils to some spare evo x coils they had. Mike tried advancing timing, retarding timing, lowering boost, nothing seems to help, so I'm going to leave the car at PRS so they can look into the issue more. I think they are going to try swaping out the injectors also.\

I will keep you updated when I find out more.

I almost forgot. Track numbers sucked.

It was my first time at the track and didnt want to launch with the ACT single, so....

MY first run I ran 13.7 @120 with a 3.01(ish) 60ft

Second run I red lighted but beat the supercharged Mustang GT in the other lane who did 13.4.

The guys that were watching from the stands commented on the missfires throughout the runs.

So is it not breaking up on the dyno only on the street or both?

This issue has me very curious... I am eager to see what it ends up being. There were a couple things I wanted to look at myself once I have some time.

****! I answered this from my phone and it apparently didn't go through.


It was breaking up on dyno and street. Some pulls on dyno went great like the last one we did before the street pulls. The first street pull was horrible and completely unexpected. It started misfiring at about 5800rpm. One of the pulls on the street felt amazing and clean all the way to 8500 when I shifted. We did another directly following that one and again it was crap.

I had some break up issues with my tune as well this past fall. We added 2-3 degrees of timing and it helped soo soo much.

Here is the VD graph. It doesnt look quite as smooth as the Mustang graph did with no smoothing.

We tried adding and removing timing. We really need to address the oil in the cylinder before we try to much more. I hope it is just a valve seal.

Yea if there is oil that should for sure be your first objective. Hopefully its something simple.

Good luck man!

thanks for bringing your back down to us. We will find out whats going on with the car unfortunately there seems to be some underlying issue with the oil in the cylinder head which could be causing the erratic misfires.

We will keep the process updated for all of you following his build. I must say I haven't seen a customers car this clean from being self installed

a this might sound crazy but i had a problem like this , it was the way my fuel filter was positioned , we found out that as the car would get higher in the rpm's it would do like a fuel cut (i.e) breaking up. took us about 3hr to figure this out but the filter had a little bend in it . maybe this could be your problem
