I have been running stage 2 with an invidia catless DP and SPT catback on a TP stage 2 map for a few months and definetly had great results.
Yesterday i bought a cobb intake and airbox for the low price of $165 (used of course) and slapped it on, switched maps, datalogged, and had Eric tweak the map for me and i felt nothing on the butt dyno.
Yes i know all the stock box users will chime in saying i told you so and blah blah, just save it please. For the price i paid i saw no reason to not give it a shot.
I live in TX and it has been mid 90's the past week. I am seeing about 114 degree intake temps at wot going about 70+ MPH (this is mid day, at night i would expect them to be in the high 90's). There was not really any changes in that department between the 2 intakes.
Turbo spool sound is pretty loud but i dont care wheather its there or not.
I am not complaining here or saying 1 intake is better than another, i am just sharing my personal experience.
