i've read about the SMC mapping. that is actually a cheaper way to manage fuel under boost. gotta have bigger injectors.........which is really needed to up the boost anyway. in actuality, you can boost 8-10 psi on stock D16 with less than $200. how? here you go:
-DSM 450cc and resistor box= $30 (junkyard)
-SMC fuel management= $100
-Manual Boost controller from
www.boostvalve.com= $40
