Seems like 1 of those ones you see on ebay and other sites like that saying
15HP INCREASE, $25, Best item you could ever buy bla bla bla
But all it is, is a resistor sending a different signal
Thought of getting one for my old car at one point until i did some research and all it ended up doing was giving the signal a false reading, so it would give it more fuel
As what Vxorado said thats basicaly the same thing that happens
Im with the others on this
And the fact they have the page set as Isuzu Vehicross and you hit the year and these like even 1980s in there rofl if they were gonna sell it correctly theyd have it all done properly
