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.

So Kirkster... I was interested in the GTM SC also. Pure bolt on? So does the kit come with an ECU reflash, and therefore, no need for me to take it to a shop for tuning (since I live so far away from one)? If I have to I have to... but just wondering if the kit comes with the full flash/tune.

Yes it does come with uprev and a base tune that Sam provides. Pretty solid tune. But you will want to run it on a dyno to be sure where it is at eventually. The kits have come a long way from the 350 days where the car might not even run out of the box. No need to run right out and get a tune.

Yes it is a pure bolt on...

Wow.... thanks for the info Kirkster. So around 7k or so, plus a little bit of wrench time (how long total for the install?), and I've got myself a reliable 460whp monster? Someone you recommend at GTM to speak to?

My total wrench time was around 25~30 hours, which seems to be the typical run time for us do it yourselfers...

I would say that the 400 ~ 420whp is a realistic number for the GTM kit. That is also going to keep things conservative and hopefully in the long run keep the car going without too many problem.

Call GTM up and talk to Sam. He has been very helpful with me and I told him what I wanted to do with the car and he suggested the Oil cooler (which I was already going to do as my car ran hot in NA form), I chose the PLX stuff and the thermostatic kit on my own which is really what drove the price to the 7K mark.
