The tune that Sam sends you out of the box is pretty spot on so you can be comfortable that your car will not go boom till you get it to the shop of your choice. I took mine to ZdayZ (1800 miles all told with my 300 miles of shakedown) after Sam and a very experienced F.I. Friend looked at the logging info to ensure that the a car was running right. When I get home I am taking it in to do some dyno runs and get my aftermarket a/f welded in.

All told my kit was 7k with PLX a/f and boost gauges and an oil cooler and thermostatic kit for when it gets cold around here.

I think the power levels that I have are perfect. Not so much power that you are roasting tires, but more than enough for fun. I am not sure about the additional maintenance yet but aside from oil changes and a belt replacement I am not seeing much. Hopefully it will just run, much like my Ford Lightning.

Am I happy with it? Yes I am. Would I do it again? In a heartbeat.
