got dyno'd today

car is a 95 5.0 mods are cobra intake, fms shorty headers, 2.5 off road h with flows, bbk cai, 4.10 gear i have a tko 500 for a trans

best run was 176 hp 231 tq
other were 158 hp 224tq
160 hp 224 tq

car dies after 4 grand any ideas why? i know it is hard to say over the computer but any help would be great

this was today at the woodward dream cruise temp was 97 with 19% humidity on a roush trailor dyno

i'm happy with the tq # but the hp sucks

yeh from what i've read on here i was expecting to see above 200 now i just need to find out why it is so low and why it dies after 4000 rpm's

this was done on a roush dyno that is on a trailor that is taken to car shows and events. tehy back it up a ramp onto the trailor and lift the ramp up to even the trailor out so the car is about 5 ft in the air.

it's suppose to cost $75 for 3 pulls but the owner of the Royal Oak ford dealorship told me after my pulls not to pay him and come see him when i want to buy a new car so i'll give tony girmaldi from royal oak ford on woodward a shout out

my computer is too slow to put pictures on here so my #'s for my best pull are:
