This x1,000, I know the popular route for max whp gains seems to be downpipes after a tune, but if you keep the OE FMIC good luck holding STG2+ timing for anything longer than a single pull. One good pull through a couple gears and the OE intercooler will be useless, at that point the car is spent until it cools down. For an engine that runs so hot as is, i'm still a bit surprised at how poor the OE intercooler is. We can debate the merits of the stock airbox, whether the secondary cats do anything, etc etc...but the general crappiness of the OE intercooler is a concrete reality.
