Fast forward, found a plug wire grounding out to the dipstick tube. The fix: regap all plugs from 60 to 35, and move the dipstick further away. She's running like a champ now.

Now I guess I'm retuning it with the new injectors and now no misfire.

Why da hell were the stock injectors at 130%?!

Those the flex fuel injectors? Were they $$? 50 pounders?

LTs, and BTR cam (and 6k+ rpms) cause the high duty cycle. Flex fuels are like 50 vs 24 stock. Decaps were like 65.

Have you been able to run it hard with the 4.56s yet? Or did it start running bad right after install and now you're tuning?
Sorry read 15 pages and eyes went all wonky lol

I have been trying to take it easy. Got on it a little bit and it was down on power so it was lame. But part throttle has been nice. Now that we fixed our misfire and get the tune right im thinking its gonna be a nice driver. Meaning tow good, nice street manners etc.
