SR to LS2 coilpack help

[slow92]

I think I bypassed my original sr coilpack harness and wired each individual ls1 coil to each individual sr20 coilpack signal wire per cylinder. I think I wired one of the grounds from the ls1 coilpack harness to the original coilpack harness grounds and the other one I grounded to the chasis or motor. It is pretty straight forward and everything is wired directly into the engine harness. Everything worked flawlessly. In fact I was having spark issues when my sr was making 400whp at the upper rev limit but since the swap I had noticed a significant difference in the vehicle's acceleration across the power band.

Thank you for the input! I'm still battling my install which I never thought I had the issues I am.

Can you tell me What gap are you running? And which plugs. I just bought new ngk bkr7e and gapped at .030 I plan to test later today. Will report back any updates
