I just want to see some numbers I think though am gonna run the 64CC chambers don't want to cut into my piston yet. Once I get the Katech 402 then I'll change everything over get my heads milled with 59CC chambers and my reliefs in the new forged internals should be good enough but if i need to cut a little more i will.

Sounds like a MS4 with a cylinder out.

Actually it sounds pretty good. What suprised me was that this wasn't even EPSs biggest grind listed for the 5.7 NAs. That 236/248 ought to shake the ground as well. Bring on the dyno sheets!

No, I just swapped out the IAC with a known good one and eliminated the PCV system from the intake as well. Reset the TPS too. Still having the issue. The tuner said just bring it in they can handle trouble shooting as well. The SES is on so who knows.. it could have the answer right there too.
So late on the 12th I'll know exactly what was causing it. They seem to think it's in the tune. Probably not a vacuum leak because it doesn't do it when the car is first started. It will idle all day, but once you crack the throttle and drive it, the idle never comes down.

) i drilled my butterfly, before finding out, car ran and idled much better. cleaned the sensors and ended having to buy a new tb. it would race in neutral to 2K rpm. hell in a 35 mph zone didn't need to touch the gas pedal once
