I am installing a Nitrous Outlet Plate kit on my 2000 Camaro this weekend. I had my mail order tune set up for TR6's because that what my tuner recommended. But after a ton of reading it looks like I should be moving to a BR6EF. If I did this would I need a new tune?

I'm only running a 100 shot I just installed a wide band and I will be wiring it into my HSW MicroEdge. I was told to set the rich shut off at 11.4 A/F and the lean shut off at 12.0 A/F what are your thoughts about this?

The car has 135K on it but it runs good. I recently installed long tubes and a cat back. I'm not running any cats.

I couldn't imagine that swapping a plug 1 step colder than stock for another plug 1 step colder than stock would make enough of a change to have to do a full re-tune, but I'm sure someone with WAAY more knowledge than me will answer soon.

6's seem to be old school, most guys have moved to the 7's now from what ive seen

When I talked to my tuner I was wanting to run 7. He'll I even bought a set but they said tr6 is what they tune for.

Get a new tuner.

you dont need to retune if you go to a 7.

Well I have been with my tuner for awhile and I would like to drive to him and he would tune it with the 7's in it but I'm getting a mail order tune becaues I don't have the time to drive to him. I guess I can put the 7 in it and watch my A/F ratio.

Forget ur tuner, Forget mail order tunes, LOL. Get yourself a HPT or EFILive and Masports efi tuning book. You will never rely on anyone else to tune ur car again. It's easier than you think.

Thats great advice, some tuners would like you to think its black magic but trust me its not.

good call on the tuning I have been thinking a lot about getting the HP tuner software. I guess I will just put the 7's in it
