What side effects have you ppl experienced with the UDP's, not really concerned with the electrical power cause i am not planning on upgrading the stereo soon, but anything else go wrong.


Plus can you please say what brand you have and cost .

Also i know eurozx3 changed the afx and says it was better than focus central anyone else feel that the focus central on wasn't perfect ? because it is the most affordabole on i can fidn

i have the focus central ($115, i think) and definately noticed an increase in power (speed). really haven't noticed any difference w/ ac while driving. but when i'm just sitting in the car w/ the engine/ac on (which rarely ever happens, anyways) the vents just spit out air (not cold but not hot - just good old air). and it's extremely slow when the ac is on - but it probably did that before anyways. that's the only possible thing that wasn't great about it. definately recommend it.

Oh yeah is it easy to swicth it back to stock because the udp is one of the few mods that screws teh entire engine warranty, along with electronics and a/c.

switching pulleys is a breeze.... no bad side effects. my temp gauge is actually cooler with the afx, so the water pump pulley may spin better with it. my car ran hot a couple times with the focus central when the a/c was on. i have a mtx81000D amp, its a 1000+ watt class d sub amp with 4g wiring and have no problems electric wise with either pulley

I have the FC got them for $90 from FC. WEll he had them on Ebay but still came from FC. Anyway I can feel that the car responds very nicely to this mod and would say get them ASAP. As for warranty I cant see them causing a problem because the car isn't having to work as hard. So how can it be bad for the car?
