General NOTES.

Just wanted to post a couple notes after a few weeks after installing everything. If you buy the same injectors I did or even the expensive Bosch ones, you may encounter some issues like I did.

First off. The truck ran great. About 50 miles of driving the truck threw a code. P0172 and P0175 which are bank 1 and 2 rich codes. After doing tons of research, checking fuel rail pressure and talking to Five0motorsports that sells the Bosch injectors, turns out my MAF sensor was bad. I also installed a 195 degree thermostat. I've driven 250 miles since and haven't thrown a code. I also now get a whopping 12.7 MPG with 285/75/16 mud tires going 70 MPH. And yes that was calculated by pencil and paper.

Injectors I installed. Update. Do not buy these injectors. Please get the ones from FiveOmotorsports. I had to redo this job as the amazon injectors failed.
