boost was slipping at 6300~ rpm, rich afr . the port injector manifold pressure compensation looked pretty aggressive , ie as manifold pressure increased the port injector open time is modified. Steve:I looked at a couple of other boosted tunes i have and they were less aggressive so i made a couple of changes to Port injector manifold pressure compensation put maf scaling back to original changed pi/di to use a bit less port than previous tune originally you were only 20% port I put it to 50 but ive backed it off to 35% port at upper rpm as were not like 14 psi so we dont need to rely on port as much if the 02 sensor doesnt change anything try this V3 tune
