Is there any reason you can't just log a few runs through the gears? I'd just get the car warmed up and log some 1-4 runs and see what your knock counts are. You sound like you've got the boost leak check out of the way and 1200' elevation should not be a big enough difference for that kind off falloff. I'd save myself the dyno time and cost and just log some runs as suggested in a realistic setting.

 

^^^ well i dont have the cable to log it for one... so i will have to wait till, get with my friend to do some logs, and as for the dyno it is only 60.00 for 3 pulls and AFR, not big deal there.

 

I'm seriously not trying to be a jerk, just offering thoughts here. Why not save the $60 this time around, then spend the $80 on the required cable and you can log data any time you please and within a relatively short time you'd at least be able to break down tps, knock counts, ipw, timing, along with other parameters that will be beneficial in helping you determine if your car is healthy or not? I'm not saying at all dyno's can't be a useful tool, but I prefer live action to a simulated run any day.

 

Good Luck finding what ups.. But it would def help if you posted the time slip #'s. 60,330,660 et and mph and 1320 et and mph. What RPM are you shifting at?
