I tried to do a search for this company, ADS, that sells a plug in tuner for $120, for my 96'Z, & came up empty. Is there anybody out there that knows anything about this product?

 

Plug in tuners are all worthless IMO.

 

ADS used to make proms and such during the thirdgen days, they were comparable to the hypertech chips and junk back then. I had a ADS Superchip in my 86 IROC. Don't know anything about their plug in tuners specifically, but for LT1s they seem to generally be overpriced crap. Just get a mailorder tune from PCMforless or Madz28...
