A common misconception is that if I make an "x" amount of boost it will make that much power when this isnt true, good tuning to utilize the boost is what makes power, and there are so many variables from fuel tuning to how efficient the turbocharger system is. for example lets compare a boondocker sidemount turbo apex (the most inefficent set up IMO) to a midmount turbo apex with equal length headers, external wastegate, stand alone ECM TUNED PROPERLY! water to air intercooler.
I can garuntee heads up @ 15psi it would be a landslide win for high end tur bo kit. inefficient set up = heat=less power. good flowing exhaust and dense cold charge air equal big power. But all of that is useless if the compressed air can't be mixed perfectly and at the right time. Look at how many people have a turbo kit with a cheap dobeck style fuel controller are now using either Vipecs or boost it fuel systems and they work amazing, I went from dobeck to boost it and it was night and day difference and the turbo set up itself never changed. Cheap fuel injection systems do not account for enough variables to consistently run well in our constant chaning environment and running conditions.
you boost gauge is good, your sled was just never tuned optimally till now
