highest read hp195.50
@4000rpm's. this was before my magnaflow high flow converters. i can feel more power with the new ones, is louder also. havnt dyno'd after results yet. was told it was average for my 2000 5.4, it did gain 12 hp and torque by removing the aifilter fyi.
when i get my intake im taking it in again and dynoing just the cats and then switch out the intake and see where it sits and then in time i will get the chip. and in time after that when my motors crapped out, rebuild and a blower!
