EVO Red pump gas/race gas dyno numbers.
To get correct wtq/whp numbers, the pulls should be made in the gear that is closest to 1.00:1. For us, it's 4th gear. If it's a 6 speed it would probably be 5th gear. By doing the pull at 1:1 ratio, the MECHANICAL ADVANTAGE of the transmission doesn't play a part in the final numbers. That's why all of the tuning runs we made were in 3rd gear, less stress on the motor, but still good to tune to. Then, when final pulls are made, the whp/wtq will increase, due to less mechanical advantage. Think of it in the same light as a fulcrum and lever. The longer the lever, the more mechanical advantage you have and the less amount of work is required to move the other end(weight/resistance). 1:1 it's the same force (resistance) on each side. For tuning, 3rd is fine, then 4th for final tuning. At least, that's how I've done it and the same for DB. I think I've seen several other Top tuners do the same. Put a car on a dyno in 3rd, do a pull. Then, go to 4th and do a pull. Big difference in numbers.
Yeah, I thought he hit like 602 or something without the spray at like 27psi? Huh well you most certainly know better than me 
Anyways, he was a major inspiration to me and all the DSM community(especially fwd guys). R.I.P Smithoid

Dave,
If I ask real nice, can you post a boost plot of the pump gas tune?
I know you probably don't log it on the dyno, an AEM screenshot of the MAP sensor and RPM would be good enough.
Pretty please?

I didn't know that most of the final pulls coming out of BR were 4th gear. I understand what you are saying about the effect on peak numbers, but using 4th rather than 3rd gear will result in a dyno graph showing a broader power band since the turbo will spool at a lower RPM in 4th than 3rd, and I'm pretty confident that most posted dyno graphs on EvoM are 3rd gear pulls (at least with VIIIs).
at which boost did the car make 440 on pump?
In the first post, it's said to be 30 psi. Then on the post
that includes the dyno plot with race gas, it says 38 psi on both pump and race gas.
Just want to make sure
