Trifecta Tune, i do have to say this is a good tune for the money. After all, they are not using a dyno and are a sponser here. Like I said, if you dont have 400.00 to spend on a tune Trifecta is a good tune for the money.

I believe my comp is pulling timing out on the top, maybe even earler. I have a power loss and i think it may be the noiser valvetrain. I need a LT4 knock sensor. And a cam and valve train swap. Curt

 

I'm not taking anything away from trifecta at all. I thought my car ran great. My main reason for posting was to show how benificial a dyno tune can be even after a mail order.

 

That's a great price. Dyno tunes go for $800 for GM vehicles around here.

 

I didn't even know there was a good shop in columbus let alone 10 mins from my work. I will have to swing in there and check em out

 

I'm near there - where does a tune cost $800? My Z06 was tuned for $250.
