Hey all!

Here is my 2015 GT with just a Corsa cat back and 3:73's. (no tune and no other mods besides lowering springs)

The car is now in storage and it will have Kooks 1-7/8x3 catless long tubes, JLT intake, Lund Racing Flexfuel/E85 tune and a few other small things in spring.

Video description and video is of a 4th gear pull.
The sheets below show 4th gear followed by a 5th gear pull that i don't have a video for.

Love the color. Love the stance. Love the black wheels with the blue paint. Just a really good looking GT. So you're going to stretching her legs this summer. :rockon:

My thoughts as well.
I go off of the other graph if i am asked. 378/354 seem more realistic.
I was told the dyno didnt like the speed the car got up to in 5th so they did the other 5 pulls in 4th. 421/355 was in 5th which is supposed to be 1:1 in the 2015's.
Quantum is local shop the specializes in Subarus and Mitsubishis. The excuse was the dyno wasn't calibrated above 140mph.

Ah gotcha. Why NGauge over X4? Constant Real time data logging?

Lund Racing doesn't use the X4 for new customers. I believe they still support it with previous ones.
the nGauge seems like the way to go for all of the possible monitor functions.
I am a huge fan of the Accessport and the nGauge was the closest there was.

The car looks good.

Thank you!
Its still a work in progress.

Looks great, I'm assuming extreme's? how are you liking them?

Yes. Corsa Extreme catback. For s550’s they do a full catback with a double xpipe (to help with drone I guess).
I love the catback. 70mph in 6th on the freeway you can barely tell its there but drop to 4th and its worlds different.

Thanks everyone!
It was kinda surprising to me as well when I found out 5th was 1:1. It is a m6 car.

It's been that way in the MT82 since 2011. I prefer it that way myself, I never saw the point of having two overdrives. 6th gear in my 2012 was plenty tall

Nice pics and great numbers, gotta get mine on the rollers soon. I for one wish 4th gear was 1:1. 3.73's are just too much gear for the MT82 IMO. That and 4th is a little too much gear at road courses. If and when the money allows, a Magnum XL will replace mine. I loved the T56 in my LS1's and 4.10's worked great with them.
