The "X"'s hold torque better than horsepower.

hi a noob question, is it the drop-in filter that made the power gains or the gst boost assembly or both?

[evopaul]

I would hate to see what a FPred and all the bolt-on's and GST tune would net!!!!
These x's have the potential to make really good horsepower.

The power gains came from the combination of all those parts + the tune....

Read more of GST's threads and you'll start to understand what a great tune does to an evo...
