Just bought an auto 15 frs with 68k miles through auction. 1 owner and in pretty good condition. I would have to imagine around 25-30K on the supercharger
Problem I had when I was driving home was that in 2nd gear usually the car once it reaches 2.8k-3k rpm it acts like a fuel cut or compressor surge. I noticed that my belt was missing a complete rib all the way around. My new belt should be here tomorrow so I'll know if that was it. Any other ideas on what it could be? I'll replace the belt tomorrow and figure out how to upload a youtube video if it keeps up tomorrow
Thanks in advance

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

Wanted to touch base on these posts I made. I ended up taking it to TRL to have some inserts installed as well as a new tune/FF kit.
I want to say I'm not 100% positive but I believe a tune fixed the problem. Seems to run flawless at any point of the RPM band after a new FNG from delicious
