I have an L59 in a Tahoe and I'm doing a cam swap for the first time. It's a summit sum-8701R1 and I know that tuning is necessary. Now I have managed to clone a p59 with a couple mods, as in no vats and speed cut off raised. But I have no idea what it is I need to do for the cam swap. I do have shorty headers on it as well. I do t know if that's important for tuning. Any assistance is appreciated. Thanks
