PCM tunes

[theplayer]

Can some of you with PCM tunes (like wait4me, westers or pcmforless) check and make sure your odometers are logging correct mileage? I am thinking about getting a tuned PCM. I want to make sure these places don't program the PCMs to log more miles to make it look like you are getting better gas mileage. I guess the best way to check is by the mile markers on the highway. I would appreciate feedback.

I got a westers, speedo and mileage is right on. Don't expect big mpg gains, it's going to be negligible but do expect a huge power and performance gain.

Wait4me here. When I first got it, the speedo was WAY off, like almost 10mph. Sent it back and it is dead on speed now. Mileage gained about 1mpg and I have tracked every tankful since I bought the hoe 162k ago.

I got a Jesse tune in August and speedo is right on by GPS gained 2 mpg city & 2 mpg hwy until the cold weather hit and lost an average of 1.5 mpg.

Wait4Me tune for nine months and about 15,000 miles

 

Solo improved almost 2 MPG running Premium gas on the Hwy. and running legal to slightly over posted speeds to keep with the flow of traffis.

 

Towing a 5,300 LB travel trailer only increased 2/10 ths

City driving about 2/10ths using mostly regular. I'm not really sure if the city driving is really a improvement, but when you consider That I'm more likely to put my foot in it for the rush I now get with the tune....it ain't no worse than before the tune, but more fun.

 

I'm in Tampa for the weekend and put 320 miles on the Yukon and the tank is only down to 1/2, and thats driving normal with the flow of traffic. Speaking of normal flow I-75 from Naples to Tampa was like a crowd going to a concert Bumper to Bumper. Atleast it was not like turn 2 at Daytona!

 

I had Jesse correct for the 17" wheels and tires over the stock 16". the speedo is correct now where before the tune it was slower than I was actually going.

Anybody else with the wait4me economy tune? If mileage is better your odometer correct?

Since my tune my mileage went down but I think that is because I can't stay out of it.

Westers tune. Mileage improvements are not noticeable for the daily ride to work ... too many lights, stop and go traffic and people that jump in front of you. However, when I took a trip to Wildwood NJ I did notice significant MPG increase and was quite pleased. However, that's a rare occassion because being on a highway in NJ doing 60 for 2 hours is almost impossible to do daily.
