Now here's a question. I bought mine from Amazon last month. That website said it would work with my Tbird. It was only when I went to the site that it said it would not work. Is it possible that I skip the upgrade and just directly plug and play? Also, thanks for the quick response. Can't wait to show my upgrades.

You definitely don't want to update the device! If you do it erases all the codes from SCT, although you could also get custom tunes from a third party and use those.

cutouts are cool but not for rpm past 3000 sitting still
do it and let me know
and do some nitrous info too
Thanks, Donny. Actually, I went to a well-respected muffler shop here and he convinced me to straight pipe it. It's legal and it sounds BAAAADDDDD! Yet, when you get to cruising speed, no matter what gear, the noise goes way, way, down - enough to talk and listen to great music.

The SCT tuners are almost always better than the factory programming and well worth the money and usually pay for themselves IMHO! Same goes for the cold air intake. Just the money you save on air filters makes the cold air intake worth it! The SCT is the best tuner, so spring for it, if you have the cash.
How does the various tuners affect emissions? I live in Arizona

My muffler guy recommended straight pipes (legal in Va.). I really like them. Yes, they are "loud" but go easy on the pedal and not bad. It has been my experience that conversation/music does not start until you reach a constant cruise (in any gear). Also, being a Boomer, I have learned how to use the SST and really like it. Almost like the good ol/ days.

I got mine from Summitt up here in Ohio, the sound is incredible, I have a 3.9 in mine, That's the Jaguar Engine and Tranie, also had Head problems and had to get new gaskets at 45000 miles and they had to shave the heads, more power and the Borla gives more as well. 0-60 in about 4 seconds or less, very fast now
did you do any performance porting while the heads were off? thats were the power comes in.

I guess I'm in the "leave it alone" camp with my '02.....$400 for a tuner (won't even discuss the Borla $$$) to get what, a 10% horsepower boost on a 230hp engine ? So, you're at 250hp approx, 260hp maybe ? Does anybody have actual dyno numbers or other stats ?

The car's are anemic compared to my Corvettes but I love them as "relaxed" boulevard cruisers...

Just installed my K&N to go with my Borla Exhaust. The exhaust note is just fine and with the K&N, you can hear the rush of air into the engine. Had a small issue while installing the K&N but some engineering of existing valve venting hose it looks and runs like it should. Next step is the SCT while in carintine.
