I think I will just use what I have and if I decide it is not enough then I will ebay sell the chip and buy from somewhere else. I just up and decided to spend some money on my truck today so I did it with out consulting my fellow explorer forum guys for their opinion's first. I got the exhaust, chip, cold air intake, a passport 8500, and some nice new floor mats with Xplorer embroidered into them and some cleaning products. I think I will be satisfied with the performance products considering I am just looking for a little extra something for power. I have some 20's and 6-12's in the back which kind of take from my power due to the weight. I spent around 1,300.00 today on Autoanything.com
