Dont stress too much about driving it around untuned after your mods. I put in a 100CPI Ballistic, new cooler and 4" intake and drove it constantly for 3 weeks without a problem before I could make it to the tuner. JUST DONT HIT BOOST, which is easier said than done, but if you have a boost gauge and some self control it is possible. Too many people treat the motor as if its made from egg shells and are scared to drive the car anywhere. Just be careful with it and youll be able to drive it around without a problem, just dont flog it as that's when youll get problems
