Think steve has pretty much nailed the questions on the head for me really, only thing is i dont know the answers thats why im here? i know a few things about REVO and maybe 2 answerd refering to Jabba, but the important ones
Customer Service / Reputation / Feedback from others
Quality of product (think of testing, development time on their product etc
Which is gonna be best?
Cheers CC for the info on the Exhause all seems pretty clear now LOL
Nothing wrong IMO with any of the products you have listed......You made a great argument i your first post for a tuner that suits your needs......sounds like the sensible logical option for you.
