You "DO NOT NEED A MAFIA" with a 2.8 pulley with a stock blower. 1st, turn your Maf to the 10 O'clock position. 2nd, log your FPDC on your predator. Its under gas/accel (its under FP). 3rd, ask Scott for a new tune minus the mafia. 4th, get a wideband for peace of mind anyway. If Scott went over rthe tune several times, its not the tuner. They use the same base tunes as a starting point ofr every car. They meaning every mail order tuner thats worth their salt, AKA Jon Lund, Chris Johnson, James @ RWTD, Rick @ Amazon etc. If you do not get it fixed from trying what I typed above, take it to performance solutions and get a tune from Devon. He and Dan know their shit over there and give member discounts. I know that they will not stop until they figure out whats causing the problem. Gene
I didn't realize he only had a 2.8. Ditch the mafia.
