IDGAF what people are telling you on that other site, $59 is JUST fine, you need to set the injector voltage compensation table properly, until you do this, you will have problems with any code you run. There have been many discussions about resolution loss using a 3 BAR MAP vs a 2 BAR MAP and the difference is so small, you will NOT notice it. Look for these discussion in the DIY PROM forum, and on $59. IIRC, there are 255 steps in the ADC logic for converting the MAP voltage to values within the ECM, this equates to .157 PSI per step, using a 3 BAR MAP sensor and .118 PSIG per step using a 2 BAR MAP sensor. That's a difference of .039 PSIG per step. If you REALLY believe that that little difference is going to make a hill of beans of difference, by all means, switch to a 2 BAR MAP sensor, and a different code, but there are reasons why people don't use $8F as a base for tuning.
Just go MS, you're only going to continue to have problems unless you choose to tune the thing correctly.
