I can't get a hold of my tuner, and was curious if I would need to retune if I replaced my 58trim (revhard stage 2) 450 max hp turbo with a t67 max 750hp running same boost settings? Right now I'm running 15-17 psi getting 400hp. Tuned on a hot *** day, 750 rc's and 2.5 inch piping.

 

I am pretty sure I replied to your email.

It will be definitely in your best interest to atleast get it checked out. It will need touched up.

 

It would probably be good enough to get around on (without hitting boost) but I would definitely get another tune.

You could easily do the install, then drive the car on the current tune to another tuner.

 

gotcha. thanks

 

Shoot me another email or pm me on here if you want to set something up. It should be a relatively easy retune.
