My car has a dang gremlin i cant get rid of...NEED HELP!!!
Ok so heres the deal.. I have a turbo maxima specs will be listed below... So any who when I am driving i get a sputter around 3800-4000 rpms and it continues as long as i am WOT...As it is sputtering my AFR is good around 12.7. Now if i am under partial throttle it will go all the way to red line until i shift.. WHATS THE DARN DEAL????? I thought maybe my A32 MAF was maxing out so i installed a Z32 MAF and the problem still persists. Its almost like the car is cutting back fuel or more like its running only 5 cylinders.. The car drives normal daily driven and the AFR looks good just under WOT i get this problem... The weird thing is even though its sputtering its gaining/holding boost and still has some power and AFR looks bueno!!!!!
Summary of fuel/air mods: 255 walbro fp, 370cc injectors, Z32 MAF and a Aem wideband... Anyone that can please help me resolve this problem or has had similar problems please help!!!!!!

Its running on the wastegate spring which is 7 psi.... and i have no idea what the FP is because i have no FPR.... Should i get a FPR and if so what should the stock FPR be at when and if i get one???? I do have a FMU but i have no idea what the calibration is on it so i took it off cause it was running to rich on the stock injectors....

I have no idea on the timing.... I am using a VAFC2 for minor adjustments but i plan on getting a emange blue.
Just took it for another test drive and if i have it at partial throttle it has no sputter and runs like a beast but as soon as i go WOT sputter instantly...

Ok i did research and know what spark blow out it... That might be my problem cause i do have 2 step colder plugs but i am running a .043 gap... I am going to reduce the gap to about .035 to see if that helps out with the problem
