I had the stealth2 tuner before EFIlive. Its a quadzilla product and I was very happy, but i didnt have the product you are talking about. Just save your money and buy EFIlive. If you have a laptop you can still get V1 for $550.
The only reason that I would like something other than EFIlive is for the ability to change settings on the fly - that and I really have no reason (yet) to record 1/4 times, etc. or mess with more advanced tuning. I'm mostly looking for some quick and easy moderate power gains. Thanks for the input!
With EFI you can change settings on the fly... You can switch between two tunes with V1, and you can get a 5 tune switch with V2. And whatever vendor you buy your tuning from will supply you with a tune to get you rolling.
