Default CAR STUTTERS in 4th gear with full throttle!

trying to figure out...got a gsr boosted with 10 pounds, and when im in full throttle the car stutters in third but mostly fourth gear and fifth. and after i get in VTECH the car stutters, i'm thinkin it's an oil pressure issue not really sure could i be right?

sounds like a tuning problem, what are you using for management?

fmu with 10 lbs is why your car is running like shit. and yeah, i've got a vafc, but it's currently tuning my NA motor... IMO, good engine management needs to come either before or at the same time a turbo is installed. too often people add it as an afterthought.

You're awfully brave to blindly trust an FMU without anything else..
