I have a 2017 Camaro ss1le and I did a stage 3 GPI cam swap and I've had a couple of rounds of tuning and the car seems to be dialed in well now. The issue I was initially having was rev match seemed to mess the tune up or something but I discovered recently that I had a loose connection on one of my spark plug wires. I was having an issue in first gear with initial acceleration but now since I replaced the wires and made sure they are all connected really well that issue has gone away. What I'm getting at is is anyone having issues with using rev match after doing a cam swap and after tuning with the same year (16-18 really)? Or was it likely the loose spark wire connection? Mine is an M6

Only issue I found is that it allows the car to stall easier if going quickly into neutral after a pull with rematch on. Other then that no. But I also noticed my launch control doesn't work anymore. It revs all the way to 7400. Haven't even tried NLS yet.

Who tuned your car? I don't have any issues with my GPI tune. I can push in the clutch at any rpm and it'll settle to idle right away.

Mine doesn't have any stalling issues it just seemed like whenever I would use Auto rev match that the tune would sort of mess up but now I'm thinking it was just that loose spark plug wire connection. Wanted to see if anyone had similar experience. I've been rev matching manually and it works fine. Now that I have solid connection on every single wire I was thinking about using Auto rev match again but I'm afraid if it might mess up the tune or something then have to get it retuned

Its why I haven't done any engine mods. All runs prefect at 73k miles. I don't trust or even know anyone in my area to do a cam swap or dependable tune without effing something up.

GPI tuned the car, both ben and Ryan worked on it. the stalling issue was fixed by raising the DEFC (Decel fuel cutoff) to 2k rpm. So essentially anything 2k rpm and under while cruising the fuel stays on. But now it catches every time.

Yep, I still have the same issue. While under normal acceleration with rev match on, you can see the car pulling massive amounts of timing in the log. I have been told there's a table somewhere (specifically on 1LE cars) that we can't access where torque management is trying to pull power.

Carolina Performance (shitty tune) and Charles Barber of v8muscle.net (semi-shitty tune). Thanks I'll likely bite the bullet and get gpi to tune it. Did they tune yours remotely or in person? and who tuned it specifically? Ryan? thanks

I didn't even know that was a thing. Like, HP tuners just didn't crack the ECU software fully? I want to go run a log now with and without rev matching enabled and overlap the playback lol. I don't think I have any issues that are there or not there with rev matching, but if I'm getting robbed of timing I'd like to be aware. I'll go back to heel-toe.
