hi all got a problem with me car, its running 2wd cosworth l6 ecu did have a stg2 ggr chip and would only run 20/22 psi then hit over boost. i got 3bar map to go on and it wouldnt run with it. was told i need a stage 3 chip to run 3bar map sensor so i brought a ahmed bayoo 330bhp chip for it and it still wont fuckin run with the 3bar map. when you stari it up it revs its self up then revs drop off and it cuts out. you can keep it running if you keep reving it but that ent right. engine spec is wrc accrilite pistons,acl race bearins, arp bolt kit,wrc ml head gasget, standerd cams, 7.2:1 comp ratio. t4 turbo, external waist gate. i want to be running 25 30 psi can any one help or give addvice on wot to do. i dont want to spend 700 on a map sesion as i cant afford that kind of brass

 

does any one know what the output of the sensors are? and could you test yours then simulate to the ECU to test?
