"I was looking to add some cheap power to my tahoe, because i already had flowmasters, AEM intake and Hypertech chip. The trottle body spacer added a little bit of torque and is helping on gas a little, by maybe 1mpg.About to take trip, so I'll be able to test the mpg there. I'd say it's worth what you pay for it. It's not amazing and it doesn't make your eyes wide open, but the power is definately there. Good choice if you're not looking to spoend too much money for power." —Robert W from Lynchburg, VA bought a Jet Power-Flow TBI Spacer for a 1999 Chevy Tahoe, 5.7L V8, 8th digit of VIN = R.
