Default Bolt on tune?

Does anyone have a bolt on tune (LT's, ORY, CAI, 160* t-stat) that they would want to share?

A better way IMO is to get a cable, use TTS datamaster to collect data, and get help to 'tweak' your tune. Tuning is not that hard given some help and allows you to make changes to shift points etc that suit your taste.

A free tune still requires a cable, and software to load the tune...

Good luck

I have the cable, tunerpro, and winflash but I haven't gotten tunerpro to work yet. I was more or less looking for a tune that was in the ballpark so I could tweak that a bit. At the current time I think my tune has already been messed with, but not necessarily to my benefit. The car used to have a supercharger on it at one point, and at another point it had a rear mount turbo on it. haha

And just to add, you can get a lot of info at lt1pcmtuning.com on self tuning. It can be overwhelming if you get too deep into it, but with bolt ons I would think you could just advance the timing a couple degrees, adjust the fuel via MAF tables, shift points, fan on/off temps, eliminate whatever you may have deleted and you'll probably see gains. Definitely want to datalog it and watch for knock when adjusting the spark advance.

EDIT: I don't know about tunerpro, but tunercats sent me a stock tune for my application. Stock would probably be the best place to start unless you find someone with a bolt on tune that will share it with you.

Year and tranny info would help your quest in finding someone to share a tune. Post it up!
