Did some DIY tuning on my car today with my temporary vf36p20 turbo, it was running into the low 10:1 AFR\'s at WOT so I leaned it out a bit up top.
Not too sure if the AFR\'s are ok coming on boost, between 13.5:1 and 11:1, but I run a G4 knock link and haven\'t seen any knock so I guess its all good.
Just wanted to see the difference between my modified VF turbo and a factory one before I go to twin scroll with the modified one. Still trying to figure out how I want it to perform.
My modified one was lacking a little response down low but pulled hard to redline, but the vf36p20 has the response I like but falls off up top. Im hoping twin scroll on my modified turbo will get the best of both.
