The only thing on my exhaust that is 2.5 is the muffler. And the run was in 3rd gear. Im waiting for my bud to set up his new scanner. should have it up soon.

I hit my peak torque around 3400rpm. then a steady drop until 5500rpm.
Peak HP is later in the rpm.

Even if it's just your muffler inlet that's 2.5, it's not good to bottleneck the exhaust. Think of traffic on the highway and what happens when you lose a lane. You have good flow, up to the bottleneck... Only a certain amount of cars can pass through the bottleneck no matter how freeflowing it is before that.

That's what I have on my N/A above 4k rpm. This and loud whistle to go with it too...:icon_mad:

That's the problem right there, you're supposed to dyno in 4th, that's the 1:1 ratio on the supra. Cudos for whoever guessed it earlier :D

Ah alright. I will remember that next time. It was my first dyno run. I just drove by and it was free for members so I thought I might as well throw it on the dyno and see how she did. How much different would it have been in 4th looking at my 3rd gear numbers? Any idea?
