JET Performance Power Shift Controller


Recommended Posts

Posted

I've been looking at this for sometime now and was looking for some advice if anybody thinks this will work, on summitracing.com they have this JET Performance Power Shift Controller for the 4l80e and this is what it says it'll do: "Plug these JET Power Shift controllers into your automatic transmission wiring harness and you can choose from four different shift firmness settings: Stock, Stage I (for around-town driving), Stage II (with a more aggressive feel), and Race. The Power Shifts are compatible with the JET Power-Servo kits for an extremely firm shift." do you guys think this would help waken my 04 sierra 2500 up? i already have the superchip in my truck but wondering would this help also?

Total waste of money.

 

What is the "superchip" you have in your truck?

 

Your best bet is to get a tune if you are looking for better performance. Take whatever 'chips' you currently have plugged into or spliced into any wires and throw them in the trash.
