hi guys i dont know if anyone can help me but here goes, i have a 1990 escort rs turbo s2, fitted with a 2.1 zvh EFI Turbo Engine, i,ve changed everything to fiesta turbo spec i.e the ecu (ofab) map sensor, act and engine wiring loom. Its got an motorsport fuel pump aswell. problem is it wont run properly ive had it at a tuners garage for weeks he cant figure out what is wrong. He can get the car to idle perfect but it wont rev at all seems like its not getting enough fuel through. He thinks its down to it being a 2.1 and the ecu still thinking its a 1.6. If this is the case will the 195 chip and beige injectors make any difference as ive just purchased them to see if it helps. Any help would be great. thanks peeps
