Of course you would lose bottom end torque in the process and I believe 98% of the people here would be more than happy to have prodigymb's numbers. :) I know I would.

In the OPs case, the car will pull hard until 5500 then it will feel bland after that whereas the Evoms's dyno posted will pull hard all the way through to just about red-line with even better low end tq. That's a big difference in my book.

-Your comparing charts from 2 different cars, on 2 different dyno's that read completely different, on 2 different days.
-You dont know how the tunes differ and why.
-The non epl chart posted has a very artificial power spike with a sharp drop. I would say this drop would make the non epl car feel far more "bland".
-Both cars make with in 5-7 hps of each other at redline.
-The scaling is different, favoring the non epl chart because of short rpm range, smaller width of chart, and starting scale at 110 hp.
-A stock car makes 405 on the dyno of the non epl car... a stock car makes 330 on our dyno. So in reality the OP's car is making more power.

This thread is not really a good debate of whats really going on power band wise. There are just too many variables.

Why don't you just set your rev limiter to 5500 since you're not making any more power after that. You can save even more gas. ;)

It's all RELATIVE. OK, 2 different dyno curves, apples to oranges, I get all that. BUT, if the dynos were an ACCURATE representation of peformance the one with flat HP will feel bland COMPARED to the other which continuously increases.

u must have a heck of a 996 if 800 crank from 5-7.1k feels bland to u ;)
