nope not all highway but not a lot of real stop and go either, I drive about 70 usually and not real light footed. Gained about 2 mpg going stage 2, and driving the same (you will probably loose a little right off the bat cause you will drive it harder) stay out of boosting it all the time and you get WAY better mileage. 80mph=bad mileage 70mph=ok mileage 60 mph= good milage. At 80mph you are constantly boosting a little, way worse than the vac you pull at lower speeds.
I usually get about 310-325 miles before the light is on in mixed driving, I think the stage 2 is more efficient due to no cats or high flow cat....
sweet..i can't wait to buy it
i'm definitely interested in engine management. i'm a firm believer that you don't need major engine mods to increase horsepower, to me engine management means the ability to better control the engine you have now, something much more valuable than a mod with a simple hp increase.
yeah 80mph sucks. i really wish i had a 6th gear so that i can stay with VERY little boost. but meh..that won't be happening until my stock tranny blows and i get the RA gear set. oh, and is it worth investing money into a turbo gauge? or ANY sort of gauge for that matter? that empty space underneath my head unit looks kinda lonely...i was hoping i could put something there that's useful, any ideas?
