i will speak first hand from stand alone ecus.

they need LOTS of dyno time to be perfect under both regular driving and high boost.

my wallet can also speak to you about that =/

you can tune for only high boost and that will be fine, but daily driving will suxor

actually if you got like a greddy EGT and a greddy wideband you owuld probably be ok.

 

thanx for all the knowladge.......i think i will go with JWT when the time comes.....(I plan on doin all the power upgrades all at one time)

 

I'm just dissapointed in your vehicle of choice.
