ROW air boxes and MAFs - shifting issues
Just installed some ROW airboxes which included new MAFs.
First cold start after install and the car shuddered a bit before settling to idle. It drove great with plenty of power up top, but was popping a ton on decel. Also at times the shifting felt 'off' in all modes - it would respond to my inputs, but shifting was way slow and pronounced (almost increased rpm in the current gear before shifting).
The second cold start was better, but when it settled to idle it seemed quieter than usual. It again drove just fine, but the shifting still felt slightly off. Not as pronounced as the first drive.
Also have AR headers and a EC v5 tune.
Is it just adapting and how long should it take? Should I try a battery disconnect?
Thanks and happy 4th!

These cars are finicky Drive more and let it adapt. I put in 100 octane today and the car felt off with slow shifting. The more I drove the better it got. The shifting is getting better.
