thanks for the help but I have read the sticky and I know your supposed to do at least a downpipe, high flo cat, colder plugs, thermostat and ecu etc... but I noticed everyone says for 3.4 pulley. On a couple sites that sell the pulleys they say 3.5 is ok for stock and from what people say the 3.5 and 3.4 is night and day difference... thats why I was wondering thats all...

Also where can I get a scanner and whats the best one ?

Thanks again, Nick
