nope...crap at best search K&N here and see the problems also rovers use closed loop injection systems using O2 sensors to adjust fuel . 14 to 1 is the ideal ratio . the closed loop system is "centered" allowing it to compensate for changes in the weather and altitude both of these changes varies the oxygen content of the air that the motor is breathing. once you start increasing the amount of fuel you move the system from its initial centered "mapping" this will limit its ability to compensate causing flodding and overly rich conditions. now seeing as these trucks are known for valve and carbon problems that last thing you want to do is run it around overly rich. ontop of all this, motors need to be balenced as far as flow characteristics. if you open up the intake for better flow and add more fuel, you still have the plugged up little exhaust system limiting performance. so IMHO....crap MM | ||

they thom, isn't the perfect stoichiometric air/fuel mixture 14.7 to 1? (hee,hee,hee) michael, look at is this way a K&N filter is typically $50, and the power chip that rover connection sells is around $400. so i'm thinkin' you should run, not walk away from this shady pitch, sounds sleezy to me. if not over oiled, K&N filters are great, but i would leave it at that. powerchips have yet to be fully proven on their own, let alone without a pile of additional upgrades. marc | ||

I have heard good things about rovertek... but unless all of these chips are hot, 99 bucks sounds almost too good to be true. I have bought a chip off of ebay for another car and it turned out to be a piece of junk | ||

Thats not a chip. It's a resistor pack. They trick the air temp sensor into thinking the air running past it is colder/denser. Therefore advancing timing and adjusting fueling. Chips, Real EPROMS, have been working well for me for the past four years. I have them in both my Classics. Buddy of mine has one in his 38A and his 4.0 Disco. No problems. Works great. FWIW |
