Sad stock dyno results...

I cannot remember if that truck will lock the converter in 3rd or not, but if it did not lock the converter you can loose a good bit right there, like 10-15%.

I think there is something to the lockup thing :hehe: Overdrive lockup run.

W O W .
Big difference, now it seems almost too high :confused:
 
Yep, Looks like I got a spike in the dyno speed sensor which made the 185 reading... more like 180ish. It does that every so often, I think I need to clean the rpm pickup.
 
So most of you guys suggest for an auto, locking up the T.C. in 4th and I'm assuming depending on the amount they load the dyno, use the brakes and drop RPM's down to 1300-1500???
