Reduce Boost (Pulley) without Re-tuning?

[Corbic]

Car is currently running 21psi on a KB2.2 Gen 1. Looking to get out of the ragged edge right now, can I drop it down to 19psi (or whatever is recommended) without the car running hella rich? Would I need to have the car re-tuned?

Unless your tune is garbage you'll be fine.

Best to stick it on a dyno to verify everything's good.

Less boost is OK Corbic! It won't run rich!

If the car has been tuned properly you should be able to drop boost without a tune change. Of course it is always best to put the car on the dyno and check it before beating it up on the street.

Widebands are $140 bucks on EBay Corbic, worth the investment!

Sweet! So do a 4th gear pull from a 40mph roll, and go WOT and it should hold 11.5!

Corbic, its always OK to decrease boost! When you increase boost it will hold 11.5 as long as you don't exceed your injectors and fuel supply! So you can increase boost and not need a retune, as long as your injectors ad fuel supply can keep up!
I have 60lbs injectors with a KB BAP! I'm at 610HP at the flywheel, and 518rwhp! I've got room to increase a little bit!

Can we please now ban the 3rd grader, for insulting outside of SD? I think we’ve seen every possible angle of his stanced out ecoboost at this point.

TWO of your posts have been deleted, and I have sent you a PM, to which no reply is needed....or wanted. Read it carefully and follow the instructions.

That escalated quickly.
