let us know how the SD mapping works out for you. i plan on going SD soon as well, i think i might just retune at 28-29psi if the car will take it and than look into a SD tune on 93/e85

Well. Fwiw the 3d SD map I downloaded used your exact values... I enabled cl and drove for a bit ended up on -5 and -12 l/m .. with maf I'm +- 1% both of them after 550 miles

well what i thinking is that since SD is using another input for air the scaling will need to be adjusted for the new parameters. good thing is that they are not far off in SD

I have the very same problem. I have no idea why my MAF reads around 60Hz at idle.

I unplugged the MAF and the idle got steady, but very rich. With the MAF plugged the engine speed and A/F are unstable. It will go as high as 1500RPM, hold there for 4 or 5 sec and then go down to 1000RPM, with no throttle input. Timing also varies a lot.
