First off, I own a '95 5-speed SC. I just finished the exhaust consisting of custom downtubes, no cats, Magnaflow resonator, single 3" to two 2.5" Dynomax mufflers. I should have some 3.27 gears soon and I have 75mm Pro-M MAF to install but I need a chip since it was setup for 42lb injectors. What should I do next? I noticed the group buy on pulleys and I was wondering if I should go with the 5% or 10% overdrive. I would like to buy used performance parts if possible so I can save some money. Thanks, Brandon
