Ebay chips?
I'm considering a chip for my v6, and I think I'll go with one from Troyer based on all the positive feedback. I'm relatively uneducated about how they work, but the search feature has been a big help. What are all those chips under $20 on eBay? Some of them claim up to 40 HP. What are they and why are they so cheap?

Hi Spitfire,
Steer clear - those are *not* performance chips. They're just a resistor to trick the PCM into thinking it's colder outside than what it really is, in order to override the PCM's normal operations of it's IAT spark modifier (the most sensitive and important spark modifier), to force more spark advance under all conditions, no matter what. Bad idea.
Sometimes they work, sometimes they don't, but even when they do, that's a dangerous trick to play and isn't tuning - that's just trying to trick the PCM to always force more spark no matter what - something no bona fide tuner would ever do like that.
You're not the first person to ask about that gimmick - that game has been going on for years, and has been discussed here numerous times.
Just remember, there are no shortcuts to proper tuning - the way to improve performance via altering what the PCM does is through proper R&D and actual tuning - not by tricks or gimmicks that deliberately skew the PCM's incoming data and don't actually alter one single bit of the actual code the PCM runs on.
Glad to hear you're making good use of the SEARCH feature - it's very handy & helps anyone get up to speed much quicker.
Best of luck whatever you decide!
