Rob im almost postive i met this guy at a couple meets down in the southside area if his wiring is a mess/rats nest under the dash/wires dangling everywhere i know him lol. And dannygsx you can get away with the lifters the 3g revised ones are the way to go tho youll love how quiet things get. you might be able to get away with adding some lucas to quiet them down for the day your tuning it. But the dreaded idle surge up n down up n down ive been there at least once with every dsm i had. Id check boost leaks first soapy water cant beat a free fix, then check you BIS screw on the throttle body their known to leak. If none of this works check the ISC. 70% of my dsm's all needed it replaced. good look let us know how the new tune feels
