I posted a similar topic months ago, but have switched to carburation. let me know what you all think
 
Maybe about 300 at the wheels.
I used performace trends engine analyzer and got 330hp and 320 trq. But this program was also a bit low for my truck, but showed the curves perfectly. So I'm guessing it estimates a bit low.
I dynoed 225 at the wheels, and the program estimates 250hp, but at the same rpm range. So this gives you an idea.
