You just don't get it:frusty:if both are capable drivers a tuned Eco WOULD be faster. Stock as it sits no,unless his buddies aren't great drivers and he is.my last car was a turbo 4 too. i know what it's like to go from 220 awhp to 349 awhp with just intake, exhaust, tune and fuel upgrades.
you spouting all this BS to the OP saying that it's so easy to beat his buddies is not helping him. i really doubt that he would with just a tune as long as his buddies are capable drivers.
That jlp had a 50/50 mix.Thats also a mid 12 way faster than he'd need to be,and who cares that's the beauty of a modern turbo car a splash of fuel and a map switch and you've got an animal when you need it. With Just a tune it is possible to hit 12's on 93.why don't you get informed and go look at some tune only Dyno numbers.there isnt alot right now because the cars new but tunes are starting to show up. Drift office has some great tune numbers as well as others.Look at the power numbers it shouldn't be that hard to understand.is that with or w/o race fuel in the tank?
