Ok so there is a guy selling a SCT XF3 tuner on criagslist locally. However when I check you website you have 2 different listings, one for a 96-98 and then 99-04. Is there really a difference in the tuner? The reason I ask is because his is for 96-98 and I have a 01.

 

According to SCT's website there is no difference. Both groupings are covered by Part#3000. AM does however have them listed as different part numbers distinguished by initial model year per grouping (38018GXX) which leads me to believe it is actually the same part number. I'm willing to bet there is no difference.

 

Now if only I had $200 to buy it.
