Partial Throttle tune goes BESERK!
ok so yesterday me and luiggi went driving around to tune the idle and partial throttle and a little bit of boost... we fixed the idle cause it was running a flat 10 for some reason then we started doing partial throttle, fuel trims were put almost exactly on point and then we started doing WOT pulls, during the WOT pulls it would break up everytime after like 4 seconds on the gas and he wasnt sure why cause the fueling was damn near perfect but it would break up, so i was like forget it i have to wait for my bigger injectors anyway so well save the WOT tuning for later.. (i was only at like 60% on 700's when we started doing the WOT pulls, wasnt trying to make power just get a clean pull) so shortly after doing the WOT i started doing partial throttle and it was INSTANT breakup.. and then after driving around a little more it went back to being normal.. Sometimes when im doing a partial throttle tad bit boost it breaks up instantly and other times it doesnt.. its like my map is being deleted and then goes back on or something.. and i swear im building boost extremely fast for some reason even faster than my old smaller turbo, like in 4th gear at like 50-60 at 3k.. ill barely be pressing the gas and itll build like 10 pounds like super fast.. with the smaller turbo it didnt even do that.. idk whats going on, anyone got any reasons for the weird breakups occuring? i just need to get all my ____ together and get on a dyno for him to sit down and relax and tune so we can perfect it.
also sometimes my truboost will read weirdly.. like at idle -8 vaccum or if im pressing the gas it seems like it will go into vacuum more or something (only happens when the weird crap happens) do you think my sensors went bad?
