A while back, I emailed these yahoos to prove their gains with some dyno results. I did not get a response, so I decided to try again. This time I got a response:

"We do a money-back guarantee. We don't rely on Dyno's, if your car doesn't show improvements on the dyno, or you don't save gas, you send it back for a full refund."
Thank you!

Really? You don't rely on dyno's? That's the first and foremost best way to check and see what kind of gains you are netting! Hopefully more people won't get ripped off!

 

Thanks for the g force chip info. If it smells crap then it must be crap.

 

It is junk. It won't do anything but lighten your wallet.

 

While I wont say G-Force is a good or bad brand, there are many variables that you don't see on a dyno or at the track. I will wager that 99.99% of people can't properly use a dyno or track numbers as a tool to decide if what they have done to their vehicle has actually been effectual; including a majority of dyno operators. I'm sure G-Force is of the same opinion. They would get returns at the rate of about 25%, same as the battery industry gets for the same reasons. People just have a lack of understanding on how to read numbers other than face value.

 

With no real life data to back it up, it is snake oil. If it doesn't give more performance or better mileage??? What is it supposed to do? up to 75hp and 8mpg??
I will stick with a tried and proven Diablosport Predator myself. I would even use a Superchips if I didn't have my DSP, but none of these $49.95 eBay hoaxes. Usually nothing but a 4.7K ohm resister that does in the IAT to fool the PCM into thinking the incoming air is 20* cooler than it is and richens up the mixture a little. AKA powerwire.
