really if i it is 3" its costing me power? how much? im pretty sure it is 3", the previous owner had it bought and installed by a pro aparrently... maybe the ecu is giving enough fuel and air for that particular size?

you say 14psi can be run on a stock engine, but is it safe?? if i ran 14psi on mine, with the specs i have, and if i bought a nice full front mount intercooler would i be ok? or would the time of the engine be limited until it blows?
