I don't have a cable to do a log unfortunately. The PO didn't include the cable when he traded it in to the dealer. I'm taking it to the racers line up in Concord CA if it's tune related. Hopefully they can tell me if it's a JRSC carb tune or some off the shelf tune that went bad. I previously wanted flex fuel but I'd rather get this sorted out before I have him install the kit. I'll see if he can save some logs so I can post them. I ran out of time yesterday to take it for a drive so I'll try today. Hopefully something simple like a belt slip from running 1 less rib on the belt

I did forget to mention. If I'm in D mode, with or without sport or traction mode engaged it does it more frequently. Usually in 2nd gear. Anything less than 50-60% tps (I'm assuming) it seems to do it. It'll pull like normal but once it hits 3k in 2nd gear it just bounces off 3k until I take my foot off the pedal for a second then give it gas and it pulls like normal through the entire power band.

I'm not sure what information ECUTEK shows, trans values, etc but once I figure out what's causing this I'll be sure to report back with logs

Thanks again
