2G Dual 255 pumps on stock motor

[Qzach96]

Picked up a gsx eclipse, pretty stripped interior and bay, all egr and emissions stuff is gone. Fuel pressure solenoid bypassed it's a pretty basic set up, and for some reason has dual 255 pumps. I'm getting a weird fuel cut at different results depending how hard your in the throttle maf is new. Any ideas?

What turbo and boost is it running? What does it have to tune with? And what size injectors, does it have a afpr?

Few things u need to check to get u in the right track to see what's going on. What are u tuning with? Do u have an afr? What timing are u running? Fuel type? What plugs and gap as well as boost level?

Stock everything besides the pumps. The goal was to run 16 how it is or get bigger turbo and injectors and run e85. But I wanna fix it before I start all of that. It's a 95 so I was planning on getting just an eprom until I can get dsm link.

Hey guys today I noticed that I overboosted right before fuel cut. Thinking wastegate rod is bent or stock or something

Check that and the vacuum lines for the actuator. Make sure p.o. Didn't rig somthing up stupid to try and make more boost . You can't run much more than 15-16 without fuel cut on stock 450's and no way to tune. Your better off lowering to 14 and not having issues till you can mod properly. I would just leave the pumps as is or remove one. You definitely don't need 2 255's with a t-2small haha are the pumps rewired yet?

I checked the vacuum lines and nothing seems rigged up. Fuel pressure solenoid was bypassed I hooked that back up. I'll take it for a drive and let you guys know
