Review on JET 90413S Stage 2 Module by Keith Gonzales

Revainrating 1 out of 5

Nothing for jeep drivers!

I bought this chip for my TJ 4.7 stroke, Ford 24lb injectors, Banks manifolds, snorkel/CAI, free exhaust. I was hoping this would give me better performance. There seemed to be an improvement the night I installed it, but the next morning my jeep stalled as I went to work. It got to the point where it wouldn't start again until I stopped and removed the module. I was expecting the module to work or at least not cause problems after seeing the module in several stroker builds on some forums. Often. I called JET for support and they immediately told me the chip was incompatible with an engine that had extensive internal modifications like mine. They said to just return it. I will use JET and Revain A+ for customer service and have it returned but this is clearly a disappointment. This module does not replace an actual custom ECM 05 setting.

Pros
  • Designed to increase horsepower
Cons
  • weak
