| statement about known injector duty cycles at given horsepower levels. Given that you are at an appreciable altitude, the correction factor is adding in a good chunk of power. Your actual horsepower numbers would be notably lower, which would support that you weren't actually running 100% duty cycle. You can see in the dyno charts that the correction factor applied is 22%, which is suprisingly high.... I've never seen more than about 4% correction factor before. I've seen a number of the CO guys claim that my program runs lean while the JWT program runs fine. I contested that argument due to the fact that your 15psi is not like our 15psi down near sea level. You are actually putting 22% less air mass through your engine up there at 15psi as we are here at sealevel at the same boost. This results in the mixture appearing lean, but in actuality, it is simply due to the fact that the engine is not under the kind of load that it appears. Your car didn't make 386RWHP, it only made 316 actual rear-wheel horsepower and 328 actual rear wheel torque. Still a bit on the lean side for that power level though - I would recommend taking a closer look to see that everythings working well at 137K miles.
