Recent review 7-30-17. Well I installed the MPFI unit just to see MPG would increase... Well unfortunately I don't see an increase yet... Would admit I've been driving my Tahoe everyday with the AC on... City/highway driving... Highest recording MPG on OEM CSFI was15.58... People have reported 2-3 MPG increase since they converted over to MPFI. Could be true just that maybe they had a problem with the original CSFI poppet unit... I'm not saying that the MPFI is a bad unit. I just don't see an MPG increase yet...

I bought this product about 6 months ago to replace the old problematic poppet style injector and with 174,000 miles made my truck run like new you can't even feel it running its that smooth It also gave the truck a little more power and better gas mileage if your spider injector is bad I highly recommend you spend the extra money and buy this updated spider injection instead of the old style replacement

Arrived within two weeks from Canada. Part was exactly as listed (new). Part was OEM GM in the box complete. Came with gaskets and bracket. Installed in 2 1/2 hours, and cleared up the idle, gave better gas mileage (15 to 19 highway), and cleared the check engine light for PA inspection/emissions. Pay close attention to injector install procedure included with the kit! Will buy again.
