i think American Muscle does...when i got my tunes, they said anytime i'm going to get an inspection, use the 87 or 89 tunes...don't know if that's different for long tubes or not...give 'em a call and see what they say

 

You have Cats. Big difference.

All they do for you is turn the rear O2's on. Any other time other than inspection their tunes default to having them off.

 

i thought i read he had cats too

 

He has headers, so its either high-flow or O/R

 

I do have high flow cats

 

well, i broke down and bought the tuner, they had a special combo with the cai , so i bit the bullet and got it with the jlt cai. put the tune in and installed the cai and man what a difference. This thing breathes fire now ! The guys from am got it right for sure . Although i wasnt happy about shelling out the bucks , i am happy with the outcome.

 

A tuner should always be one of the first 2 things you do. It comes in real handy, and allows you to just get updated tunes and toss them on.

 

Awesome man! Enjoy the new power!

 

Great investment, and you won't miss the money when you stomp on the gas! Congrats!

 

Right after i installed the tune , i took it for a run down the high way, sure enough an unmarked cruiser picked me up and started tailing me on the way back to the house, so , I went home , picked up a check and went to the bank and decided to try another run, sure enough, a state cop in a cruiser got on my tail ( different one this time ) so i really havent had the chance to open her up. Hopefully this weekend i'll give it a good run.
