Thoughts on this product??

It is a fuel injector spacer, it was linked off a TBI spacer. I'm> guessing the idea is similar to the tbi spacer. My thoughts, were this> is a bit overkill. TBI spacers seem to be in question and im not sure> what moving the injector up more is gonna do. Any Ideas? Absolute zero. On relection, no: about a couple of of your hours and $15 are lost. I tried one my '94 K1500 Suburban 5.7 TBI and there was zero change in mileage and/or performance. I even bought a Hypertech chip for this unit and I thought it had a slight perceptible performance increase off bottom end. Zero mileage difference there either. I took it out later and couldn't tell the difference after. So the original "difference" may have been just a perception after spending $300 or so. The new Hypertech programmers actually make a real difference. Use on on my '04 Avalanche Z71.

Slightly, very slightly Your engine will still use the same amount fuel.
