The Too High PSI port kit is great and not too hard to dial in. You have to tune the car similar to how you would tune a car that is leaning on meth for fuel. DSX is coming out with a port kit, hopefully some time this year, that should negate the need to tune a separate controller for the injectors. I'm going to put the DSX Port Kit on my personal ZL1 as soon as Dave will sell me one lol.

Point being, now that there are port offerings, you can get further with power for similar or less money than upgrading the DI stuff. One the ZL1's you have to buy a different lid for the supercharger or you will have issues with the blower hitting the hood.
