I have a stock computer from a 1987 GN. This has been modified for 55lb injectors (Quad Air) and has the chip. (This was removed when I went to the FAST system and I just found it.
55s are not 50s , if you need a chip i would suggest TurboTweak Home and youll get a modern chip custom tailored for your needs and your cars combo as no two will be alike , a custom chipafest for your car rather than a buying a chip because its cheap that you really dont know what its setup for , theres more to a chip than just being burned for your injectors ,
All pm's replied to. As far as the chip goes it would be best to get a chip specifically for your setup. This chip is in and should be ok for temporary use until you can get one.
Yes collect89 the 55# injectors will be for sale when the parts arrive at my home. Contact me (or whoever buys the ECM) if you're interested in the injectors.
