Hello Gang, looking to lean on some good advice.
QUESTION: What is the most ideal A/F Ratio I should target for on a custom Tune for my N/A Mach 1? Lots of opinions hoping to get some good advise / experience.
SETUP: '03 with 5speed (Steel Crank), no power adders, Flat Top Manely's with Manley H beam rods, Intake and Heads Polished, PHP Intake spacer, Accufab Twin 60 TB, Comp Cam 106100s straight up no cam advance. Factory Fuel and Coil packs, JLT Intake.

Let me know your thoughts everyone, this forum is irreplaceable for such an incredible wealth of knowledge out there .. thanks in advance.
