Alright I have searched google quite a bit and cannot find a solution to my specific issue(s) Mods: evo3 16g, VRSF FMIC, 1g Bov, 2g Stock non eprom ecu, wally 255, stm fuel pump rewire, fuel lab AFPR, Stock 450cc injectors, I have a 97 GST
Ever since I installed the walbro I have had a problem with the car not going over 3k rpm it will free rev to 5500+ i just didn't red line it because I don't like to.. I set my fuel pressure with vacuum line off and covered (with my thumb) to 43 psi.. People locally say boost leak but I didnt have one before I changed the fuel pump to the 255 I recently changed the fuel filter thinking maybe that was it.. I am lost.. this problem is not being picked up by the ecu at all there are just my egr codes coming up that's it.. The boost gauge is picking up 10 psi at the manifold..
Best describing how the car acts at idle or revving the car it works beautifully.. once I get moving in 1st gear Ill try to get on it once the car gets just past 3k it just wont go.. it stutters halts It sounds like it wants to backfire it has once .. I can also hear boost building and it just feels like alot of pressure building once i let off I can hear the bov working but the car just wont push past tried 2nd gear and nothing as well I checked to see if it was my maf and thats not it the car barley runs unplugged.. Please help thanks
Also will be making a boost leak tester tomorrow. but i really feel thats not the issue but i am doing it for peace of mind
