Do you have a way of scanning the car and seeing if you get any knock retard with the LT1 module? I would put the LT1 module in, watch for retard and try a new LT4 module if you are seeing knock. No need for a new LT4 module if you don't have knock!

Keep the stock knock module and have someone with a scantool go with you for a ride and see if you have any knock. If you do, try the LT4 km.
Also, you have a pm.

Thanx again Dan.
After my runs tomorrow at the track, I'll let u know what's going on from there.
I would like to get a run with a scan tool and get a good look at timing and fuel curves with this new programming.
