Hi everyone,
I'm new to tuning and recently finished rebuilding the LS7 in my 2007 Corvette C6 Z06 with the following cam:
Katech "Touring" - 227/245 @ 0.050, .630/.630 lift, 116.5 + 4.5 LSA
When I start the engine, it cranks, catches, and then immediately dies unless I blip the throttle. I've tried doubling the Startup Airflow tables, but this only helps with cold starts (ECT ~ 77F). I'm also getting noticeable misfires at idle.
Is there a to-do checklist (airflow, fueling, spark, etc.) that people follow after installing a cam that's bigger than stock using HP Tuners? Alternatively, are there any proven starting-point values that work well with the Katech Touring Cam or similar specs?
Any advice, logs, or tune examples would be greatly appreciated?thanks in advance!
