ive converted my erst 2 efi and im having trouble with it,its got a jamsport head with a piper cam,ive also got a 195 chip and beige injectors,its running ofac management,the problem is if i try 2 move the car it coughs and splutters a bit but will clear but then when the turbo starts coming on boost it tries cutting out then if i ift of it returns 2 idle ok,i thought it might b due 2 not being setup so i tried it with blue injectors and unplugged the chip but still the same just ticks over a bit better,any body got any ideas please
