After having a superchip on my 01 for a lil over a year i fianally bought a comp box. I bought it some what premature, but i have a dtt on the way. I know my 9 cm housing will be way too small for the comp box. I have been looking at a PDR HX 40/16, as well as 4" exhaust. Is there better turbos for the money, or is the hx 40 a good buy. Also, can i run my superchip and comp box together, like not all the time, just for showing off or whatever. :-laf As usual, input is always loved!!!! Thanx
