Boost Reading From PCM Accurate?
Just wondering how accurate the boost reading is from the pcm. I added an Edge Evolution programmer/gauges and stock reading was 15 psi, 80 hp program jumped it up to 18 psi and I just installed the WW2 and turbo master waste gate controller and I only got 19 psi. All testing done on same street at same location to try to be as accurate as possible. I will say that the difference from just the tune to the tune with the WW2 was noticeable. It pulled real strong and smooth after the WW2 install and getting on the go pedal at 1600 rpm in 6th, no surge, it just pulls nice. So I am just wondering how accurate the reading is. Thanks.
