Good work Boosted! I agree in what seems to be the theory/direction you are choosing going after the converter. No doubts the motor is making more power because the front half ISN'T there but the 660 ET/MPH is promising! While it might be interesting to know the current ICL, I'd probably leave it where it is and get the converter adjusted. I'd guess that alone will get you deep into the 6.5s Your cam is small, a bigger cam will get you another .1 easily. That would put you in the 6.3's with typical tuning IMO.
