Not to sure the tuning process was a bit stuffed round he got half tune done on 16 then couldnt go further due to a missing 02 sensor when i swapped to twinscroll set up went back week later and the mac valve i had died fml

So max power was 200 awhp on 12psi

However i popped a boost tee in and was sitting round 15 for powercruise nd antilag cruise

Till the hills run nd cold air spiked that up whoops somewhere round 17-19psi at a guess was to busy watchin the road nd by time i noticed was knockin * facepalm* my bad eh the stock heads/cams were holding power back massively
