02 with 27K Only trouble I have had is with a cold weather miss when temp is colder then 40 deg out
no one has been able to fix it and blam is pushed off on to performance parts. So far Marco's ecm has made the bigger improvment on my cold weather miss or surge. Only time will tell with winter comming on and how well it going to run this winter when temps drop.
