Apex Turbo Question

[Pastor]

What is the optimal Spark Plug gap running 18 lbs. boost?


Thanks for your help.

Stock works best, that's what the mapping was designed for, I tried changing the gap and ended up with some very different AF readings that I couldn't compensate for, mind you this was with an MCX kit which is non adjustable.

What is the stock reccomended gap?

Just as a counterpoint. At 12#s boost my Apex ran like crap with the stock gap. Following the formula that can be found elsewhere on the net for decreasing the gap as boost is added I gapped mine down to .020 and it made a world of difference. I have the Boondocker turbo with the Pure Logic fuel control system. Does it work for everybody, I have no idea.
