Boost numbers
Does anybody know if the boost numbers seen in the cluster are total engine boost or are they the larger turbo's boost numbers? Where do they tap into for the gauge? Do these turbo's run wastegates? Im tryin to squeeze some more boost outta the turbinators before I use a tuner. Any input is appreciated

Those are actual boost numbers in the CAC tubes, and no there is no waste gate, with the VGT turbo a waste gate is not used. Only way to get more boost is to reprogram the PCM or replace the turbos.

Since a VGT turbo is controlled by the PCM, the only way to increase the boost output is to re-program the PCM. Also more boost is not beneficial unless you can also increase the fuel delivered to each cylinder.

Well I already have the fuel situation figured out. I know the "more air needs more fuel" situation but I didnt know what turbo situation i was workin with.
Theoretically I could mod the smaller turbine wheel and maybe housing to produce more air.= at lower boost. All things I will toy with in the near future. I am debating wether or not to go with the SCT or Superchips tuner.....Such a hard life, lol
