I'm looking for a unit that can tune only fuel that will work best on my s2000 anyone heard of anything?...Ive done some research and came across a company by the name of Perfect Power...They seem to know what they are talking about anyone heard of another fuel tuner that does an awesome job? Please let me know...

 

AEM's plug and play unit.

There are a lot of piggybacks out there, but they can be very difficult to tune correctly if you have major changes.

I have seen great results with the Apex-i Neo. They are affordable and not that hard to tune. Just add a little dyno time and you are set!

 

i think you need to be more speific about what are you trying to do, you can get a FPR for lowly 50 bucks to a full tuned stand alone for couple of grand easy.
