    I put one on my 90, did not see much difference. I did some before and after testing with an accelerometer, but it changes your shift points, so i dont know if the shown improvements were all that correct. It seemed to feel a bit more responsive, but very minor.

    Very dusty and dirty K5 sitting in my driveway!!!

    i have read different opinions. i installed one on mine and noticed a difference in throtle response and power. i was very well pleased with mine. very easy to install. my K5 is a 87 with a 350 tbi.

    i haven't had a chance to see. it seem to have helped a little.
    it sure did not make it worse. my K5 has been in the body shop for 5 weeks. the guy said it would take only 2 weeks.!!!!

    I think they are a rip off personally for that kinda money... plus you have to fight w/ the brackets and getting all the cables to hook up and not bind. Yuck. But for 20 the injector spacers seem to be a decent buy and scientifically make sense, just my $.02
