Fuel Cut in 4th 10psi!!?? WTF?!!??
10psi, WOT, Greddy Profec B II Set for 10psi, 12psi warning, Peter Ferrel Purple Box Set Map Limit 12psi and Fuel Cut 14psi. Tuned maped for 10psi.
I'm doing WOT....1st,2nd,3rd amazing pull, 4th amazing....at around 6k car just hits a short wall and makes a weird exhaust tone...paaaaaaaa....paaaaaaaa and out of no where BWAT! I just let off gas and hoped engine was alright. Everything looked fine, vac 20inces.
WHY THE **** did i hit fuel cut at 6k rpms?
Record psi on profec 11.2

either the boost readings are a little off or something else is going on like a knock sensor issue. I say this because I am currently having knock sensor issues and hit fuel cut in 4th gear at 6k rpm at 10 psi and even lower. Same for 3rd
If the knock signal is questionable it will cause fuel cut earlier (safety feature)
