rear hp check w/o dyno

[fmd28]

I live in Guam and the Islnad/rock has no Dyno facility. More like the guy who has it doesn't wanna build it. I have a ford mustng Gt 03 is my car. I was wondering of there are products that can give me and Idea how much rhp I am getting after my mod's. I currently have a steeda profrmance package with new x-pipe and underpullies with cool air intake and a new 4.10 rack and pinon set.

I think a G-Tech might work. I've never used one before. Maybe someone else can chime in. Pearl02.

if there is a 1/4 mi track there, makes some runs and look at the trap speed and the race weight of your car. that would be your best bet.
