5th is 1:1 in both.....most tuner's do 4th because of the speed;as in a base w/3.357 diff,that's still just over 120mph.
That's what is throwing you a curve....i'll dig mine up with a 4th & 5th gear pull.
K&N drop in air filter's is only mod at this time.

Yes I thought about something like that could be the reason for low reading. the Dyno I went to have never dyno'd Zs before, so maybe they didn't know this? Ontop of that I was the last in the line for the Dyno run, they have been Dyno'ing cars all day through their so they were probably tired AF when they got mine lol.
Anyways, I will message them tomorrow to let them know.
