The previous owner of my car installed headers, ORY, catback, and cut the cats on my 2001 Trans Am. Though I understand this cars aren't meant for amazing gas mileage, it seems to run pretty rich (noticeable smell) and I'm averaging a little above 13 mpg in town. Granted Fayetteville, AR is quite hilly, but from what I read it seems like I should at least be getting a few more mpg than that. Best I've done was about 24mpg freeway. Oh also it's an M6, and he got the mail-order Frost tune.

I figured a good dynotune would help a lot with that, as well as squeeze out some extra horsepower. The only additional mod I'd like to do in the next few years would be 4.11 gears. Some day probably a cam/heads, but not in the near future.

Has anyone heard of a good dynotuner around NWA? I'd be willing to drive 2-3 hours if need be. After quite a bit of fruitless googling, I'm not sure where to go. Also I'd rather not shell out 400$ or more on a crappy tune. So thought I'd see if anyone had a good experience with something kind of close.

Thanks!

No one up here does HP Tuners or EFI Live professional tuning. I had my last one done at XP Racing in Tulsa with the old setup I had. I think he charges $250 for a bolt on car tune.

With the new setup I learned to do it myself and I am much happier. Your set up is pretty basic and if he had Frost do a tune then there might be some other minor issue.

I would be happy to take a look at it for you and help you diagnose before you spend a bunch of money on a tune. Not a professional but I have tuned my car (heads/cam/intake ls1 in a swap car in case you can't see my sig) and a couple 5.3 Silverados.

 

Thanks for the info guys! That would be awesome Thunderstruck. I'll pm you back shortly.

 

Mine did this and was a bad o2 sensor.

 

It's very possible it is the o2 sensor, we can check that out as well as the MAF and everything else.
