Alvin, few questions

[harvickgm]

well, my gas milage has seemed to go to shit lately.... can you do a tune for better gas milage under normal driving conditions, and tune it for optimum performance in PE or WOT. im going to do your 75 dollar unlimited deal. the car seems to run rich. and yesterday i downshifted and took off and a buddy of mine said that i blew out alittle black smoke at first. can you hook me up.
and also does rear end gear ratio play into your tuning???
thanks

and how long would it take to do the tune??? thanks

If you gas mileage has gone down hill recently, you may have a problem. A tune would be kind of a bandaid fix. I would fix the problem first then get a tuen. You may have O2 sensor issues.

As for the gas mileage, what are your datamaster logs showing??

[harvickgm]

the O2's are new, but with the LT's i need to do the heated O2 conversion. it has a recent tune up, but the gas milage just seems new cuz before i didnt drive to far at all, and now i drive 600 miles and its ok for the car i just want better milage.... the datalogs i need to get some new ones for the highway use and i will send them to you and alvin to look at.

[Fastbird]

Yeah, get us a datalog to look at. You may or may not be having O2 heat issues. At highway speeds, you shouldn't.

What kind of gas mileage are we talking here. At how many miles do you fill up and how much gas do it take to fill up?

[harvickgm]

it seems if i fill the tank up, it goes faster. so every morning i put anywhere between 10-15 dollars in. which is about 3.5 to 5 gallons, i do about 75 miles a day. so i guess its not too bad. it just seems bad cuz of gas prices. but im hoping a tune will work it to be alittle better.
