I have my first tune in the shop for a buddy of mine. He has built it a little bit, and the cam lopes at idle. I have not tried to perform a tune yet, but his already has a custom tune that was done mail order. His only concern is the dying at idle sometimes. When this thing is half warm, it dies a lot. One question that I have revolves around resetting the minimum air rate. This thing has about 120-140 IAC counts at idle when warm. What is the concensus about turning the idle stop screw in to raise minimum air rate, thus lowering my IAC counts, and maybe fixing his dying at idle problem? What about TPS?
Would it be better to drill a calibrated hole in the throttle plate so I can raise the min air without affecting TPS?
What are you guys doing on these?
Remember, I have zero experience with custom tunes, but I've been fixing them "factory" for years, so I understand the basic theory.
