MPFI throttle body spacer, 
November 13, 2010
By Anonymous
from Mobile AL
Pros: It was pretty easy to install.
Cons: After installation my truck was on the verge of stalling out about every 3 seconds it was running.
"I purchased this mainly as a relatively inexpensive way to pick up a little more gas mileage but more importantly to me more power.It was pretty simple and easy to install although I recommend a good set of deep sockets of the small bolt size range anyway after carefully taking my time I was really let down as my truck could barely maintain running at idle speed so I knew the adapter was the culprit as it ran fine the day before so I uninstalled it and it ran fine once again.I don't know if the fuel pump couldn't keep up with the extra air coming in but this was a frustrating expirence to say the least."

Pros: more horsepower and torque
Cons: takes to long to receive
"Installation was easy 10 to 15 min. 1 to 2 mpg saved. Can tell the difference in the get up and go, small amount of whistle. Must have some patience waiting on the product to arrive, took about 3 weeks.I am pleased with the spacer."

Great Improvement,

Pros: Easy to Install. Improved MPG!
"I just installed the Torque Curve spacer on my 2004 GMC Sierra with the 5.3L Vortec V8. There was a noticeable gain in MPG, about 2 in town. I also tow a large travel trailer and there is more power from this spacer. Very low amount of whistle, only at part throttle."

"I just purchased the torque curve spacer for my 1994 dodge ram 1500 with the 5.9L. I'm thrilled with the improvement in performance and gas gain. It also installed very easily in about 20 minutes. There is a barely noticable whistle"
