The G-Tech is somewhat accurate, but not all that accurate. I'd opt for the cooler looking, better functioning APEXi RSM-GP, which does the same as the G-Tech Pro, but promises to be more accurate. Heck when you think about it, you can take that $140 and spend it on getting your car dyno'd & tuned by a shop capable of doing so. According to the basic HP loss calculations. You lose a max of 15% of your hp, possibly a little less, through the drivetrain. So, 142hp X 15%= 21.7 Rounds upto about 22hp. So we should have about 120 hp @ the wheels. Not, bad if you ask me.
With the MHPtuning CAI, APEXi S-AFC, better spark plags, and dyno tunning for the S-AFC to make sure you running the fuel properly, I'm guessing we should be at around 135hp to the wheels, torque might be around 136 lb ft. These are just estimates mind you. The actual gains will remain to be scene until of course one of us dyno's the MP3 with those mods I listed. I'm definately having my car dyno'd when I finally get my intake, S-AFC, and experiment with different plugs.
After speaking to Racing Beat and confirming that the HP is being robbed by the cat on the exhaust manifold, I'm only hoping I can find a way to make the car quite once I get the money for a header. If there is ever a header on the market. With a header and larger diameter piping, I'm convinced our MP3's will produce some great numbers. If anyone has questions about APEXi products, I'd be more than willing to answer them, you can also call APEXi, but they're a little difficult to get through to sometimes.
Here are some pics and info on the RSM-GP and S-AFC
