[QUOTE="MRMIC2, post: 131341, member: 2637"] Hello acidburn,we meet again... First check your ECU whether it is a stock ECU?For your engine should be red toyota label.It is located in your boot covered by carpet. For the 1st/2nd Gen MR2 engine..The stock fuel pump,fuel regulator and injectors should easily take care of its fuelling below 1.1 bar boost.(430cc Sidefiring injectors) Check your Blowoff valve spring tension...make sure it is tighten as too loose will cause boost loss. As you have just installed the Supra fuel pump, installing a fuel pressure regulator gives you more control over the new fuel pressure. What are your SAFC settings?pls elaborate... The AVC-R shouldnt cause u any probs. Check for loose/leaking vacuum hoses too. Are your spark plugs the right heat range? Check spark plug cables resistance if it snapped internally. if all ok...then go for dyno to tune your afc. Hope this helps [/QUOTE]
