Adjust for J37 IM/TB

Post by Icecream5521 »

Installed j37 IM & TB & P2R manifold spacer on j35z2. Getting a MAP PSI of -8 to -10% and LTFT of 7-8. I didn't think I'd need to tune for this install. Do I? And if so, what should I do to correct this?

Fixed the problem here. Vacuum leak. But now Rev is bouncing between 1k and 2k when in park. Ideas??

Your questions would be better directed to someone who offers tuning services.
