Get it tuned for no cats and it's noticeable.

It's been tuned for over a month now lol. And to the track. Same times but 1ish mph more trap speed. Wheels and tires were also changed, different weather too

Wheels/tires went from 275/40 sumitomo htr z3 on 19x10 AMR wheels to 235/55 yokohama yk580 on 18x8.5 factory gt/cs bullits

If you didn't notice anything, then something was wrong. Tune and deleting cats are the two biggest N/A power mods

Ive heard of stock cars with no tunes making a big diff with cat deletes.

Just got the ORH on some difference in middle of rpm band. Sent off for new tune to go with the H. Will report back then.
