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.

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

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?

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.
