Supporting Mods with Programmer

[sk3322]

Is it neccessarry to upgrade to a fuel pump and bigger oil ect when adding just a chip to your truck? I've seen some people (mainly cummins) usually have the Fass system when they add a chip. Any Input?

The only thing you really need when you add a chip to your truck is gauges. Your engine tuner will work with you and tune your truck according to what you have done to it. If you have added a fuel system or a HPOS and bigger injectors, then they will tune your truck accordingly. If your truck is stock, they will tune it accordingly for that also.

If you are buying canned tunes, then you will be fine with stock fuel and oil. That is what they all take into acct.

But don't forget the gauges!

Yea I just thought it was weird because I was reading some reviews on tuners for like cummins, duramax, and powerstrokes and some of them said that they killed their injector pumps and stuff like that

But who knows it may have not been inflicted by the tuner itself, just seems like a lot of problems arise when people tune their trucks

ohh. gotcha

Yup the lift pump goes out on the dodges which kills the VP44 on the 24 valves or the CP3 on the common rails
