my A/F is bouncing from 10.5/11 to 16 on de-acceleration in gear which im assuming should be vacuum so ----?, have done a boost leak test and seems to be good. I also have random cut outs which feels as a fuel cut while cruising last a few seconds and during I can put my foot to the floor and nothing, push clutch in and release and power comes back. have an infinity, 2150CC, 6766, 2.2, DW320 fuel pump. I can go WOT to wastegate (25PSI) just fine. I'm lost

 

You're probably not falling under all of the necessary parameters for decel to activate reliably. Within the Infinity Tuner program, go to Wizards > Setup Wizard... On the left-hand side, expand the 'Advanced Setup' drop down, then click 'Accel and Decel Fuel'. On the right-hand side you'll find all the necessary options under 'Decel Fuel Cut'.

 

Ok ill check it out when I have time tonight, I only drive to certain places now because on the highway it can be scary being "random" loosing power but maybe if its not random and im tripping something I seem to not be able to replicate every time. I looked at my logs from infinity and I can see where my target is 14s and im at high 30s. voltage good, inj1 feedback good, oil pressure safety turned off so not tripping that, RPMs 3500s.

sometimes I let off and go to vacuum ---- and others I bounce back and forth until I get back on the throttle, speed up and let off the throttle again still in gear and will hit ---- like im trying to create a stronger vacuum

 

my injectors were turning off randomly from exhaust cam losing sync because the exhaust cam positioning sensor was bad.
