I've a bit of a dilemma on my hands at the moment. I have been researching heavily into both the Juicebox and the remap.
I have the following options:
Angel tuning remap
AMD Tuning remap
All of these products give similar gains, apart from th JB4 which supposedly gives another 10-15bhp ontop of Angel or AMD's figures.
Can anyone offer any advice, or first hand experiences with any of these products. Another aspect I'd like to question is the reliability post-remap on a 335i, any information would be greatly appreciated.
