What times are the pulley 2003s running on your local track?
Day to day track conditions have so very much to do with times.
I pulled 394 rwhp after sticking in the K&N filter, iced...
Frankly, unless you and I are running on the same dyno back to back, I don't really know what to make of dyno readings. I listen, but kinda say 'i wonder what that really means...'.
And I'd rather be lined up side by side at the track.
dynos to vary in many ways like brand (dynojet vs mustang) and ambient air temp, cool down on the car, ect..... my 1st pull was 375.6 and then we let it cool for 20min with a fan infront of it then it pulled the 381.9. Im still very happy with the # though. I will check the build date of it soon and let u guys know.
