View Full Version : Tactrix Openport Interface - where to get a tune?

06-20-13, 01:08 PM
So a friend of mine as above mentioned tuner interface. I was wondering where I could get an inexspensive tune, deleting the speed limiter, CAGS and maybe add a couple of HP's? My friend with the tuner already has a tune for the limiter and the 1-4 delete - I was wondering if it's even worth getting a custom tune for a stock setup, and if there is any noticable gain.

2007 CTS-V Cutoffs, KN Intake.

any ideas?

For the CAGS alone, it's worth it :) Common agreement seems to say a tune is good for maybe 20hp tops on a stock setup. If it's something you plan to do yourself (HP tuners, EFIlive, ....), it's a good place to start as you can get your hands on it without having to make big adjustments right away. If you're going to pay someone else... you might want to wait.

As far as I know, we don't have a speed limiter. Maybe I just haven't found it yet?
