I tried one on my Dakota and it didn't work and they refused
to give me a refund. Pull a twenty out of your wallet, set
it on fire and watch it burn until it is all gone, you've spent
less and got more enjoyment.
Bought 1 for my 02 Dakota 4.7 auto. Made 2 dyno pulls ( my freind has a
portable dyno he takes to car shows so some guys can have bragging rights)
1st pull without the Jet chip show a horsepower of 238. 2nd pull on
dyno with the Jet chip installed ( it only takes about 2 minutes to install
on the Dakota) showed a horsepower of 257!! 19 more HP, This is with the
stage 1 Chip, as the only mods I have are cat back exsaust and cold air
intake. Not bad for 2 min work!! But the Chips are PRICEY!!! Hope this
The Jet chip I had (stage 1) was in series with the comp. and while it
provided initial gains based on laptop dyno software eventually the
gains went away as the internal comp compensated for the chip.
