Car wont rev past 6k or 8k WOT
Hey guys,
I am having a weird hesitation or brick wall sensation with my car under WOT. To begin with, the car is a s5 jspec tII with all emissions removed with the factory turbo. I installed a FBCD by knightsports, a walbaro 255lph FP, 800cc sard injectors, and a manual boost controller to hit 8-10psi. Before I installed these I could go all the way up to the factory 8.7k fuel cut and I was only boosting 4psi (ported wastegate). In 1st gear I hit a brick wall at 6k, however my wideband says I am still running rich. In 2nd gear I sometimes hit it at 7k or 8k, and the wideband still says I am running rich. The wideband reads between 10 and 12 in both situations. I am wondering if anyone else has had the same type of setup and if its just because of the FBCD unit that I put in, or is my fuel pump not pushing enough fuel? Thanks for any help, Ricky |
