I've been having problems with my 1990 5.0 leaning out on the mid and top end. Theres is a tuning shop here that can custom make a chip for me for $347.00 and still use the stock injectores but here's what sucks. tuning is $180.00 and hour the guy says its going to take him about 2 hours to tune. So I'm looking at $600 plus. Any other alternative I can do for leaning out on top end and [COLOR=#c80000! important][COLOR=#c80000! important]computer[/color][/color] not taking out enough timing?

It currently has a [COLOR=#c80000! important][COLOR=#c80000! important]msd[/color][/color] boost controller and FMU I also just put on a 9# pulley. Supercharger is made by [COLOR=#c80000! important][COLOR=#c80000! important]powerdyne[/color][/color] so maybe 6 or 7lbs actual boost.

I was thinking I could just throw some 30lb injectors I just came across and it will compansate I can't get the MAF with the calibration tube until the 12th do you think this will do the think without going to the speed shop with a cracked piggy bank. It was supposed to be a quick project I had a chance to get a running 98 M3 for a good low price but now I not sure the supercharged pony is looking like it was the right choice. but I love the foxes cheap but finicky.

Hey guys nevermind I just put in the 30# injectors and adjusted my fuel pressure regulator and I'm running like a man on fire
