This definitely improved the performance of my TBI 350 ('95 Silverado 4x4). Its not a magic bullet, but I definitely noticed an improvement to off idle and part throttle performance. The "Butt dyno" also says that this improved launch from a full stop. I have not had the opportunity to measure performance / acceleration yet since installing, but I will be measuring and comparing to the baseline measurements I took.My truck is essentially stock, other than modifications to the air filter assembly to reduce restrictions, and a free flowing exhaust system. Installation was very quick (about 20 minutes) and made a definite improvement in the way my truck drives. I would definitely recommend to a friend.

Much better throttle response and smoother idle. Good improvement to stock.

Had my doubts about this. It was an easy install. Car was very 'punchy' at low rpm. Really woke it up at take off.

I used this on a 95 Chevy s10 4.3 tbi. Was having problems with fuel air mixture fouling my spark plugs. Seems to have helped

Very easy to install, especially when adding a spacer. I reccomend getting the TBI air flow thing (looks like a salad bowl) and the 1 inch spacer. Works great with all those parts, part throttle is worlds better, and full throttle is a little better throughout the entire powerband.

This installed easily on my 90 Brougham 5.7 TBI. I also use the gaskets to lift the injectors even higher, no adverse effects, works better than before. I did this with other "ultimate tbi mods". With the spacer and gasket it raised 1/4" and leaves more room for airflow. Injector spray is fine, no concerns.

Best deal is this 1/4" injector spacer and the higher PSI spring sold together for a few dollars more. This being said, the GM TBI injectors can handle three or more times the stock fuel pressure (14PSI) without issues. Keep this in mind when it comes time to tune.
