He's tuned a guy in russia that's about 326hp and 373tq on 93 pump gas, and the numbers were right in there with the logs.
My car with a baseline tune, and all the stock parts (no bolt ons), currently reads 300/312 on 91 pump gas when I have the tuned ECM in the car. After I get all the bolt ons back on, he's expecting to see around 340/360
isn't technology great?

Oh really... I never thought too much about the numbers, mostly just using them as a reference point, and making sure with each change that number went up. That would be awesome if its that close to actual RW numbers. Come to think of it, I remember thinking my original stock pull was pretty low (270ish ft/lbs) as I was expecting the stock rating of 295ish. Your tuner is probably correct then, considering drive train loss, 270's would be right on the money for RWT. Crap, learn something new everyday, thanks for that Jason!! (Awesome numbers on that 93 tune BTW!!)
