If I remember correctly there was another forum member with similar issues with GT350 manifold and 350 TB.
I think it ended up being the tunes no lift shift setting. Something wasn’t setup properly at upper rpm throttle settings.
Just an idea I’m not even sure if you have a manual trans

Maybe try the PMAS no tune required MAF sensor and see if that clears it up.

Curious what the result would be with the stock TB with an adapter. As stated, some have had issue with the GT350 TB.

Mine pulls hard to 8K. GT350 intake, stock TB on adapter, Roush CAI.

Wengerd has no issues getting the GT 350 87mm TB to wick out and haul the mail !

This is the route i would go. I never heard of the tuner he mentioned. I would send Wengerd an email and just ask if he could look at this for you. This sounds like it could easily be a tune issue. I know Wengerd is backed up as he is one of the top guys right now in this platform, but he will respond and give you solid advice.

ok so this file is when I was talking about me only pushing the pedal about half way keeping the car in manual mode and I got near 40 lb/min of air. second file is pedal fully down and you can see I got like 23lb/min

this was my first set up with stock intake and going up the rpm it was really bouncy like it sounded like I was blipping the throttle mid pull but my foot is all the way down lol

I am not sure who Wengerd is as I said Im still new and my tuner is like 3 years old so not big but i heard good things from them. if you can send me his email that would be great I just want my car running right again!
