Ive done quite a bit of searching and found others with a similar issue but none with a direct answer. Im new to tuning and was looking for some direction. Car is a 02 ls1 fbo m6 with a 228r cam. runs and idles great other than one small issue. when i stab the throttle or clutch in the idle drops to around 500 then comes back up to the requested 800. doesnt really hunt just drops one time and comes back up. from what ive read it has to do with base airflow, the throttle blade is opened up to .71 on the tps and IAC counts are around 40 warm, i was told this is about the limit on opening the blade. I added some base idle airflow also and havent really gained on the issue. is this a idle timing issue or do i need more base airflow? thanks.
