So I got bored on my long drive home and set up my PIDS to monitor Engine TQ and HP. These always seem pretty accurate but the ones at the rear wheels aren't worth a damn.
I will try to get to a real dyno sometime for comparison but this sounds really really close to right.
388hp/366tq at the flywheel. Only took it up to 6300 in 2nd so I might bump it up a little tomorrow and try again. However I think that's where it peaks.
Scott, if you can post your dyno graph for comparison that would be great.

I kinda use those PIDs to set my shift points. From the way i understand them, they basically measure acceleration, so when ever that HP number starts falling off, i basically know where to set my shift point...
Also if you look at the equation for HP
HP = gvmlb()*{SAE.VSS.mph}*dx({SAE.VSS.mph},6)/8226.63
There is a setting in EFILive where you can put in the vehicle weight, or i think it defaults to a certain weight based off of the VIN.
Edit -> Log File Information, click the Vehicle options tab... Updating this field will update the RWHP value..

I'll have to go back and look at the IAT's again, I forgot, It was nice out but not too cold.
Thanks for the tip Corey, I didn't know that. But I am going to bump it up a little and see if 6300 is the peak or not. more than likely is for that cam. Figure going a tad over would make up for the RPM drop on the shift.
The RWHP is always Irate, so will that fix the problem? It shows like 1100 hp at the RW and like 360ftlbs
