Does AFM bluetop have lower comp pistons than the MAP bltp?

Apolan, the difference in compression isnt staggering.. It'l most likely work okay. Especially considering you might be moving to lower compression, which has less risky than higher comp.
Do you know how many people have milled their heads down a bit and used thinner headgaskets with a stock ecu? I can think of plenty.
You can adjust for detonation with the static adjustment of your distributor, so I dont see the problem. Should you get in trouble, I do have a complete kit of 4AGE AFM stuff + ECU collecting dust here.....Which reminds me, my previous engine was originally an AFM engine too... ran just fine on ae86 map ecu and injectors..
