SR tuning help, car runs poor!

[HOOCH]

So haveing some tuning issues with my SR redtop! Car cold starts fine but the wastegate is stuck wide open, tried bypassing the boost controller with straight vacuum and still same thing. And the car is running pig rich, i have 850cc witht the pressure set at 43.5psi and at idle my A/F is in the 11sand dies when you stop, backed off the pressure a lil and its better like 12-13 but still almost dies rpms drop super low! but cruising at hwy speeds car is at like 13-14? Have already decided im replacing the wastegate with a dif one, but could use some help with the tuning!

What ECU are you using? Who tuned it?

Cruising at 13-14 AFR's is fine as well as Idle

WOT should be around 12-12.5

850 cc
z32 maf
no mention of tune worries me. Car will just be dumping fuel into engine without tune. not to mention maf readings are gonna be all over the world

[Sileighty_85]

well if its tuned for your setup then you should look in to checking for boost/Vac leaks
