I was wondering if there were significant differences in regards to tuning the two.
I don't think it will "tune" any different...just basically have dial in the boost....whereas before I had to throw timing at it to maintain anything up top..so it might affect that somehow...We will see after its all done.....I basically had to let the ECU relearn before I can go in and adjust Boost..right now...its still overboasting in 4th/5th gear..to like 24lbs....Now that I am thinking about it...It probably will affect the tune...at least on top....I will post the results after the re-tune ..
