I posted this in the injector section and they think its a tuning issue

I have a 1999 trans am with a built ls6. It put 456hp to the wheels. But it just hasnt ever ran right. It has fouled 4 sets of plugs in 50 miles. I rarely drive the car simply because it just doesnt drive right. Every time i pull the plugs they are coated in fuel. Eveb if the car just sits for a week i will try to start it and it wont even spark to crank over. I was running 42 pound injectors and pulled them off this weekend yo see if the stock injectors would work. Now it runs out of fuel. I get too about 3000rpm and it just cuts out. whats going on guys? Bad injectors? Bad tune? Please help!!!


Also this is weird, if the car sits a day or two and i start it up my trip odomoter resets to 0. also when i start the car the rev needle will redline and then go all the way back to 0 while the car idles normal.

Is my tune junk?

Sounds like a ground issue with the trip resetting

When the needles go to the top then return to normal at startup, sometimes the battery is bad.
Check the grounds and power terminals, sometimes they are corroded or loose, causing this kind of issues

Could be a bad alternator also, had a similar problem on mine but at 5k rpm. and once in a while at any rpm over 3k.

as far as tune , why not get a dyno tune from someone else. Or at least a frost tune so you can drive the car .

To try and help out a little if you are close to OKC, I will gladly evaluate the tune in your car. Run a quick datalog and look the car over to give you an idea on which way to proceed at no charge.
