i loved mine when i had it on my 2.3L 92 longbed. it was a PIA to tune to get it just right, so it wasnt running lean and dieseling when warm out. Then in NJ, winter......had to readjust it slightly as it hated cold days. other than an occasional adjustment, i got great fuel economy, and the throttle response is INSTANT...even for the 92 hp motor. You feel the difference with the weber over stock. See the Cali plate....you WILL not pass SMOG. besides that, worth the costs!!!
