Tune by mail?

**a338566** · 04-22-2007, 04:53 PM

I have found several websites that will tune your computer for you if you mail it to them. Is this a good way for a tune? I am not familiar at all with this procedure. it seems to me that it would need to be in the car for the best results, but i dont fully understand what a " Tune " is. i just know i need my rear O2 sensors deleted. Anyone with experience with this please help me out

your best results will come from a dyno tune but i do have a friend that has got a mail order tune for his LT4 setup and it was a success. since you live in lillinois i have heard that there a some good ls1 shops there. try to find a shop with a dyno that has ls1 software. good luck

I had went with a mail order tune and had great luck but yes a dyno would be more accurate. I would really say it depends on what your current mods are or planned mods.

just LT headers, true duals (no cats), and a lid currently, new pushrods in the near future

I went with the mail tune at PCMFORLESS.COM and it was great for the basic bolt on items. Once I went with a bigger cam, heads and torque converter, I had to get a dyno tune because it hard to tune the car without the car. A tune by mail is fine for the basic bolt ons or stock but I would go with a dyno tune if doing big mods. This way it can be fine tuned.

For what you are needing, a mail order tune would be fine for now. If you were doing heads/cam or something that needs timing adjustments, a/f adjustments, then it would require a dyno tune. Deleting codes like you need can be handled by any mail order tune though.
