It's about the same here today but the weather changes so unpredicibly I can't count on a cool afternoon. It can be 70* one day and 98* the next, ya know? I am too busy with my bike club during the summer anyway. A nice 68* fall day works for me!

Amazing! I noticed HP remained close @ previous peak RPM, yet TQ was 200 FT.LBS. more @ 1K less RPM's.
Some time ago!
There's your problem right there Bill...
I don't know what "well over" 900ft/lbs means but if your making 754ft/lbs at the wheel and have 20% drivetrain loss your looking at 945ft/lbs at the crank(converter) and if your seeing 25% drivetrain loss your right around 1000 ft/lbs at the crank(converter). In any case your at the limit of that converter.

My truck is nothing as all out as Parish's but I'll take that as a sincere comlpiment.
As I think about it, I never intended to make this much power, I just came to PT.net to get it running good
If this weather holds up I will be making a pass or 2 at the track in 2 weeks.

it spikes for about 750rpm, then drops to 600ft lbs. am i missing something here? thats not real world, to the pavement, torque. cool for telling your friends that your truck makes 750 ft lbs though i guess.

welcome back IMD...
Who the heck really cares about the dyno numbers anyway. They are only to compare gains from the mods made and used as a tool for tuning. Notice I have not changed the numbers in my sig? The track is where I measure against other trucks.
