Its kinda FI related, I tend to stay out of the PCM section..
I ran the HPT 2-Bar thing for a couple weeks. worked OK but I could never get the cold/hot start air/fuel right. One night it died after a burnout and couldnt get it to restart for final round - needless to say I was kinda pissed, since I ran the car for 1.5 years without issue with the MAF I just switched back and was done with it. Car never ran any faster or did anything better then it did with the stock program/MAF really, even though it was somewhat 'hacked' as some called it. I did have to runa few different tunes for major weather changes but after a while I could just adjust the fuel pressure and be close at the track..
Six of one/half dozen of the other..
