I have just installed pacesetter LT's and dont have cats or rear O2 sensors hooked up. I drove the car a little since then and the check engine light didnt come yet. I am asssuming it will in the future and am wondering what madz28 tune I should get. I also want the skip shift eliminated and performance tune. If there is anything else you think I should get please tell me because I am not to sure about what I need with the computer programming.

 

You can get a few more rwhp by getting the premium gas tuning (if you don't mind paying a little extra).

Just e-mail the guy what you just posted, he'll get you what you need. Are you mailing your pcm or do you have a cable?

 

I would check out his website, he has all of his standard services listed there and he does other things as well upon request. If you have an automatic tranny, he can firm up your shifts as well and also adjust your coolant fan on/off temp. Pretty good service for the price.
