The tech passed the car visually, but it failed out the sniffer. The car has: 2.3 whipple accufab TB 60's Tune Bassani X w/ cats Bassani catback Anyone else fail out the sniffer. They do a 15mph and 25mph test. The worst part of the test was the NO's at 15 mph. My test results: @ 15 MPH / 2015 RPM: HC - MAX=52, MEASURED=77 CO - MAX=.49, MEASURED=.10 NO - MAX=424, MEASURED=871 @ 25 MPH / 2200 RPM: HC - MAX=36, MEASURED=54 CO - MAX=.46, MEASURED=.13 NO - MAX=711, MEASURED=695 My next plan of attack is to put my stock H pipe back on. I also want to tweak the tune w/ my PRP. Any tuners out there know where to start???
