Mustang GT stock 177hp?

[9COBRA7]

Alright the story begins when i bought the G-tech pro i always wondered exactly how much it was off. well anyways i recently tested my car and my girlfriends brothers 02 gt. Basically the only thing i have to increase hp would be my exhaust and it said my car ran 285hp cant remember the torque, and thats also a 97 cobra. we ran the GT with all the same settings figuring its the same car different model and newer year, and it said it only ran a 177hp, and we made several attempts because i was shocked and the same thing kept coming up, sometimes 176. we hoped back in my car and i pulled a 284. I know GT's are slower.. but by over a 100hp, and the GTs are under 200 stock?

Did you recalibrate the G-tech each time you moved it from car to car? Something ain't right....

No I didnt recalibrate, but i didnt think its nessasary. I've ran it a few more times in my car and im still running the same as usual 285, before exhaust it said 275.

A 2000 GT should dyno between 200-220 stock depending on if it's a 5 spd or auto....

I dynoed 236/279 stock

how accurage are these insta dynos? I found one that was called g-timer... heck... if they are close enough... it would be almost worth getting one

When set up correctly and calibrated they are pretty damn close when it comes to estimating ET's, within .1 from what I've witnessed first hand. The newer G-Tech Pro is pretty accurate from what I've read and witnessed.

What about estimating hp?

What about estimating hp?

It's pretty close for the most part. You have to remember all it does is use a mathmatical formula to figure the HP. It derives the estimate based on total vehicle weight and acceleration/distance speeds/times. Kind of like what this HP calculator does: http://www.speedworldmotorplex.com/calc.htm
