After having severe igntion breakup above 8 psi, I took it to Dent Sport Garage in Norwood, MA (highly reccomended by myself!) and had it tuned for a few hours under light load conditions. Well just as I was expecting, I was still having severe break up, and the entire shop crew was puzzled as has every other shop/person I've asked for help from ... BUT - - The good news: My car made 299.4 WHP on pump gas at only 7 PSI!! We re-did all of the plug wires today and pulled the plugs and everything checked out ok... My next step is to swap igniters, and if that doesn't fix the problem, install all new wiring from the PFC to the igniter. I will keep everyone posted... Mods list below to those who are interested...

 

Im interested to see what it will do with about double that boost. That is pretty strong numbers for 7lbs and ignition issues.

 

Did you drive your car up there? over two hour away right?

 

yeah i trooped it up there.. it actually took almost 4 hours because we left around 7am and hit traffic almost the whole way there. i'm very curious how it's gonna do myself. we bumped up the PSI to 13 and it gave me an extra 60 ft/lbs of torque but that was only at 5.5k RPM or so. it was the loudest i have ever heard my car though. everyone was afraid it was gonna blow up.. it was quite scary LoL

 

If you haven't done so, get a new coil pack harness - first culprit with ignition breakup woes.

i'm not even using the harness. all of my coils are wired directly to the igniter, and my igniter, as of today, is wired directly to the ECU instead of going through the front harness.
