Better than expected
Jet products has never let me down until now... Wanted to install their tune into my 14 Sierra All Terrain, but seeing they haven't built it yet, bummer!!!! But I did install this TBI and the mass air sensor, and it took a couple days to get the computer squared away... It have not only seen an increase in power from around the 3200+ rpms, but an increase in mileage around 2 mpg local, and close to 3 mpg's on the big road... Now that's running around 1800 rpm's @ 80mph...
2017 Quicksilver GMC Sierra with Guts & Glory
K&N black hawk cold intake gave my sierra what it needed, guts & glory combine with magnaflow # 14288 's not loud just right for take offs and mid power both complement each other perfectly for my taste , you can feel the the smooth shifting and power when you press the gas . K&N instructions are very easy to follow would have taken me 30 minutes to finished but I lost the small screws from the maf senor when a gust of wind blew them and couldn't find them . Very satisfied customer!!
