I'm interested in any Canadians who have made performance mods on their GTs, and how pleased you are with the results. I'm considering what mods, if any, to do on mine, (primarily tune, intake and exhaust), but am concerned about future emissions tests, esp. in draconian Ontario. So please chip in & be specific as possible.

I have a Roto-Fab intake and SLP axle backs... I LOVE the sound and the added performane (although very mimimal with those mods) I need a tune to go along with it

my SLP's can be seen here

Thats why I love livin here in the north, no emission testing. Anyways so far put a Volant CAI love it already seen an improvement on mileage and performance. Will add the tune soon just have to find the right shop.

I have Rotofab CAI, Superchips tune and Magnaflow street series catback exhaust.

The CAI really opened up the engine sound and added some high end power. The tune really improved the shifting and woke the power up quite a bit. The exhaust really added a solid exhaust note and it sounds like it should now. I dont suspect that any of my mods would cause me to fail emmisions as my cats are still in place and my cat back exhaust has a spot for the O2 sensors.

I have a Roto-Fab, Vector tune and straight pipe axle-back so far. I kept my stock PCM just in case but I don't expect to have any problems even as I go deeper into the mods. The dealer that I use for service has always looked after me in the past.
