I don't think 75psi is normal, I only saw that much when I sprayed it with a 200shot with 2300pulse on 100overs
That's insane. I'm glad I never put a gauge in mine....probably would've threw up when it wrapped past 70. No more VVTs for me!
Not doing your truck any favors with numbers like that, more importantly what are your egt's when you are making that kind of drive pressure?
What other mods do you have done? Any aftermarket boost tubes or exhaust manifolds by any chance?
on the old ppe300 tune (33psi) i would see 1700 and on this efi tune 1500
as of now i have stock everything except emission crap. i have boost tubes and down pipe getting here this week.
Is this prior to your converter locking up or after. Your drive pressure (exhaust back pressure) should be close to a 1:1 once your converter locks. But since it's a VGT it'll change based on what your VGT duty cycle is. Either way your at a 2:1 which could lead to issues. I know you said your waiting for it to pop but I would rather gate that or lower your tune till you can get a different charger put on
