Looking at the graph, I was wondering why the runs only went up to approxiately 5700 rpm. Does the new ECU drop the rev limit? I wish I had some extra cash laying around for that. Just curious and nosey, what was the total price? I wish I could install it myself and not void my platuim warranty.
To address your question about cost - The MAF calibrator was $250 and the shop charges were $400 for install and 1.5 hour tune on dyno.
293 at the wheels equates to a 24% loss as you stated - keeping in mind I have BFG 33" tires on - I'm sure at adds a little more drivetrain loss
As far as rev limiter goes - all of the runs were done in 4th gear, so I think that is the top speed limiter kicking in there...
makes me wonder how toyota got 381.

All manufacturers state HP at the crank. Toyota's rating of 381 HP is SAE certified at the crank. 293 HP at the wheels is a 24% reduction in power from 381 which should be about right for the drivetrain loss on this truck given the mods I have done.
The new Dodge Ram is stated to have 390 HP so it probably puts down 290-300 hp at the wheels...

thanks for clearing that up. i calculated the loss myself. some reason, i didnt that 24% was that much horsepower. thanks!

why did yours get 293?? from factory they have a 24% drive train loss? or is that 293 at the crank?
He lives in Colorado.
High altitude = less denser air and loss of power.

I don't think there's an official TRD spec, but that seems about right according to the stock boost limit being set at 8 psi by the ECM. Peak boost is probably around 4000 rpm and then tapers off from there. I think TRD did there homework on the design of this blower regarding how efficient it is.

Right...But the 293 is corrected to sea level at the wheels, so altitude doesn't have much to do with this number. The parasitic drivetrain loss is a little high probably because of my wheel/tire package.

Ahhh, that makes sense!
