Hey for all you pros out there just not sure about all the OBD stuff and new harnesses and the skunk 2 harness stuff im hearing. I got a 2001 SH and i looked here to see what people do for ECU upgrades and i hear about all this complicated stuff. I thought you could just buy those chips and stuff off of ebay? What are those anyways? Basically i would like to upgrade the ECU so i make more torque and HP. Whats the ebst way and easiest way for someone like myself to go abouts doing this. Ive heard of companies who tune the chips for you and ive also seen stuff on ebay that seem really cheap, they all calim to increase horsepower and torque. So besides actually plugging my ecu into a laptop and doing all the custamizing myself, is there something relatively simple that i can do to get more performance from the ECU. Because they say that this is the cheapest way for the most horsepower gains. Any info you lads and lasses have would be greatly appreciated. Thanks!!
