i dynoed my car on the G-TECH last night just for fun and I pulled 153hp 3 times!
i mean are g-tech somewhat accurate? i have a vafc that was tuned with no bolt ons, basically stock tuning. well 3 months later, i've installed proflow throttle body, t1r tespipe, and an AEM filter in stock box. Just wondering will this decrease my power? since i have the vafc tuned when it was bone stock. but i didnt get it tuned when i installed these items. is it possible that i can be losing power? My friend's 350Z pulled 242 twice on the g-tech, so i thought it seemed pretty accurate... thanks.

 

How accurately did you input your cars gross weight? How do you know the weight?

 

I have the Gtech. Weight is the big factor. You have to factor in gas, stereo equipment, your weight, etc. Don't forget about weather. Hotter temps and altitude can play a factor as well.

 

Go to a Flying J and get your vehicle weighed.

 

2800 lbs. but i do have a system but that fills in for the spare tire and tools which will equal approx. the same.

 

I thought we were closer to 2850 plus driver?

 

Which G-Tech model was used?

 

Yeah, 2850 is with fluids and half a tank of fuel IIRC. Add yourself. Add 50 lbs. for other things like stereo equipment, books for college, another 175 or so for your buddy that's in the passenger seat.

 

its the first model. the on that looks like a radar detector...i know its not the new ones.

 

but my friend with 350 put 3200lbs. and i know it weighs a little more than that but his reading looked accurate.
