Lean After Nitrous Plate Install?
So I just went for a drive after my nitrous plate install to check and make sure everything is still good and it looks like I'm going kind of lean at WOT which was not the case before the nitrous plate install. I'm guessing that the plate changed the intake tract around a bit and I just need to recalibrate the MAF would I be correct in this train of thought or should I be looking at something else here? The only other thing that could have changed is possibly a vaccuum leak at the intake but all I did was remove and reinstall one intake manifold bolt on each side for the solenoid brackets shouldn't have caused a leak right?

This is NA just having the kit installed no other changes other then BR7EF plugs instead of TR6. I won't spray it/tune for the spray until I figure out this little issue first. I also though my LM1 may need a free air calibration, but not calibrating it in a while would make things richer not leaner right?

Drove on them so it's not gonna be accurate. I'll be on the dyno next week. Gonna check for vacuum leaks tomorrow, but it still seems like something is off. I guess I'll take it easy until then either way.

I would imagine you'd have to have a massive leak for the AFR to go lean at WOT. At WOT there's not much vacuum in the manifold, most of the air is coming in from that huge hole in the front known as the throttle body lol.
How is the AFR and fuel trims at idle?

I'm going to the dyno next Friday with a couple fresh sets of plugs to tune for the nitrous. I'll make an NA run and check the plugs to see what the hell is going on first and then go from there.
