Sct reading knocks, lean condition, random misfire
I have a super rich tuned built and blown mach. The tuner that did the car said that I am getting these codes because I'm running so rich and not to worry about them. I trust this guy about half as far as I can throw him. First do I need to worry, second what parts should I swap to try and fix the problem ? Plugs, wires, stuff like that? This guy put 100lb injectors in a car I.wanted max 600whp then tried to tune it with stock maf and blew the motor he "built" on the dyno (this guy went through three motors) I could go on and on about the incompetence of BPR (long island shop, do.not go there unless you want to pay somebody to screw up your mach). But point is I trust your opinions much more than the idiot I dealt with. Any input would be appreciated.

I would start off getting a tune you can trust!...the tuner will be able to tell you what you got that needs to be changed !

And 100lb injectors on the stock pcm dont like to idle that well. but then again find a tuner and ask him what he says.

Re: Sct reading knocks, lean condition, random misfire
I'd suggest calling McNews in Dillsburg, PA. Great guy and will talk shop as long as you are willing. He is considered one of if not the best tuner in the area. His number is 717-432-9503. He uses SCT so it will make it easier on you if that is what was used to do the current tune. To my knowledge he does not do canned tunes so if you want him to tune it, you'll have to take it to him.
