Spark tuning is spark tuning. What’s needed is someone who knows their way around the LT5 calibration. If u r looking for part throttle, then an engine dyno or driving the car around and datalogging is how u get there. There are stock spark
tables to start with.
I use a dyno for WOT tuning and after I have the driveability down first.
Other than the carbs, what else do u plan on modifying?
