Alright so after beating on it some and then taking it easy or really my normal driving my first tank was 14.7 mpg. which is in line with about what i got during the winter with the hypertech installed (anywhere from 13.5-14.5mpg)

so as long as i keep my foot out of it shouldnt hurt the mpg.

i think next year or when i get the 285's im going to go ahead and get them to remove 85% TM instead of 75%.

if gas either stays relativley the same or hopefully goes down some ( i freakin doubt it though) im might bump up to the 89 octane and see if it feels any different. they said 15-18hp for 87 and 18-24 for 89.

have a good one.

 

Sounds good!!! I just got a 93 tune and I love it!


I tried posting a topic about it but the site wont let me.

 

Yeha I know. I tried to PM and post and I get problems too. So did it take a week or 2 before the tune really adapted to the truck? What kind of mileage are you getting? And how much TM did you get? 80% like I seen some one post was recommended?

 

I have zero TM and cant tell you about the gas yet I got to stop driving like a pissed off teen first.

 

yea i wish i had gone with 80-85% removal instead of just 75%. got to wait till i get the 285's sometime to get the retune.

 

i cant post more than one or two lines, weird. anyways truck is like night and day. wish i could justify stepping up to 89 and seeing what it would do. i know its only about $4 a tank but that adds up with $500 going to the payment. oh yea, Nelson Rocks.

 

I don't know 100% what mine was backed off too, but DS said they backed it off as far as it would go without turning it off. I noticed that as soon at it hits about 1,200 rpms or so it has a kick too it and I am off.

I bumped the injector slope up a notch and now I can roll the tires when passing @ 35-45.

I want to run my 93 tune again. I want to see if I can chirp the tire through the gears.

 

Mine chirps third but I also have a vett servo.

 

so far got 101.4+- miles on the truck with the needle still slightly above 3/4 tank (6.5gals) so roughly about 15.6mpg second tank so far. normal driving nothing hard or stomping it.
