Will adding a Jet performance chip to my 4.0 SOHC kill my gas mileage or help it or what? help me out here guys. thnx

 

it gave me about 3-5MPG, doesnt kill it at all, run mid grade like suggested so you get max benefits

 

i have one for my 3.0L. its not programable, it just changes your computer timings. it hurt my milage cause i'd floor it EVERYWHERE! but overall. with the chip, intake and exhaust i went from 16 MPG to over 21MPG. as long as you try not exceed 3000RPM. which i found is possible with that chip. my truck doesnt struggle to keep up with south fl traffic.


***should run HIGH OCTANCE FUEL FOR BEST PERFORMANCE***

 

well i guess the next question would be if it is hard on the engine cause its got 76000 on it

 

not at all, it doesnt hurt it one bit, probably help it out, i put the chip in mine with about 53k

 

I thought bout the same chip but wouldn't the Superchips Flashpaq be a better investment ? Since it does allow you to update the pc if any come out.

 

the only reason why i got the module is because i couldnt find a superchip, or a programmable one for an 02 3.0L. then DCRVP told me about one like the banks w/ a PDA, but its almost 600

 

how do you like the chip

 

can you stack the chip with like a bama tuner? i know you can do it on v10 superdutys and diesels and it would be like a double power adder if you can stack it

 

...for the price its awesome!!! more power, better fuel economy. but i didnt kno about the programmer, or else i woulda spent the extra $$$ for it.

as for stacking chips, call the company. your sending different signals to your CPU. so... if those signals conflict, it may not be pretty... do a lil research, cause i have NO clue.

 

so you could deff tell a diffrence and change with all the fuel types when used? i just dont wana spend the $ for nothing

 

thats just my opinion. your more then welcome to take a road trip to fl to test drive my truck... lol kidding.. but serously. do some research. if i'd known about a programmer, i'd have done that. but for the $300 i spent on the module its definitly worth the money. the only perfornance mods i have are a k&n intake system, a single 3IN flowmaster exhaust, and an A.R.E bed lid for aerodynamics(whether it really works or not).
