car cuts out when shifting fast. my car seems to be tuned ok, thing pulls strong. recently made 505awhp at cobb tuning. car uses dsmlinkV3, a 3'' GM mass air flow as a blow through in my upper IC pipe, a omni4bar map, and pte 1000cc injectors. ive seen them log max 100% duty cycle but car had a pretty safe 11.7 AFR the whole time.
when i shift fast though, car feels like it hits major fuel cut. my friend suggested i turn down the dead time on my injectors. i currently have dead time set to 490. i sorta suspect my BOV's. i have 2 greddy type s bov's one is hooked up to recirc, and other is open vent. both adjuster scews are almost all the way tite. maybe one or two threads showing on top of each BOV. both BOV's are tight though.
so when i shift fast i think the blow off valves push air out, making air flow backwards aginst the gm sensor, like air goes through it in the oppisite direction for a second when i shift. then when i hammer the gas agin its tottally messed. i have to lift off the pedal completley then stab it agin to get it goin. this completley sucks for highway pulls and racing. any one have this problem befor? should i try lower deadtime on injectors? look into my gm maf?
