New in the 4.6 world. Helping a friend out on some research on performance mods for the Modular 2v W/PI heads.
So far he's done Mac cold air, C&L upper, 75mm TB, Cut outs on stock Hpipe.
Next on the list is gears. What seems to be the most popular ratio for the A4's? 1/4 performance not freeway!!!
FYI: Patriots ported PI's are in the near future also...
Thanks in advance!!
