Now that i can go 0-60 or 65-120 in a matter of a couple of seconds I find I drive a little slower It's kind of amusing actually, knowing i can beat most of the ricers around here makes me less inclined to waste my time showing them
I guess I'm waiting for the 'right' ******** to come along!

ps; I averaged 16.7mpg last night over a 300 mile round trip through mountain roads getting into boost a few times, is that about right?
Oh yeah, 3.73's and running at 69-75mph.

 

What gears you got man?
Im guessing 3.73s?

 

Yup! Good guess!

 

i understand completley bro. before i wanted to hot rod around squeeling tires and just seeing what the truck would do. Now after FI , i know i have the power and i do drive a little slower .....sometimes

 

Same here. The only time I really get on it is when I want to, just for fun. I did smoke a 350Z off the line the other day because he was trying to cut in front of me and merge because the lane goes from 2 to 1 after the light. I think he was really confused when he couldnt pass me.

 

It seems like that happens to me on a daily basis. I love seeing the look on their face when they can't pass a tahoe.

I drive slower too, for the most part. Your mpg seems about right. I've gotten as high as 20mpg on the highway, while cruising at 70mph, on perfectly flat roads.

 

Good thread. Saved me and everyone else another post from me.
So if I do these mods to my LQ9 6.0L: Radix, 3.0" pulley, Dynatech LT's, Snow kit, 2600 PI stall, Comp 220/570/570/115 lsa, & Nelson dyno tuned.
What kind of mileage can I expect under normal driving conditions?
I also have the 3.73 gears and factory 20's.
I drive mostly 68-70mph on normal to & from work.
I currently get an average of 16mpg with factory tune. When I was tuned by Allen, it upped that to an average of 17-18 mpg. I've been without his tune for 5 months now.

Mileage seems great

 

I know what you mean,also in the back of your mind you want the SOB to last.How did the radix effect your mileage?

 

I think I actually get a little better around town, with the tighter converter. Highway seems about the same if I stay out of it. On flat roads I seem to get about 18.5 ave. and like I stated above almost 17mpg running mixed flat/mountain roads and punching it a few times
