Its physically impossible to to have a pressure increase after both; a)plumbing which always suffers some static loss. b)cooling which increases density, therefore reducing pressure. This is the fundamental reason why you control and measure boost AFTER any cooling device if you wana know/control whats really making it to your engine. Statistically, knowing the pre-cooler figures (boost, & temp) is always handy in assessing / tuning / further modding. Furthermore this is how you measure the efficiency of your (inter)cooling system. Greater temp drop for less pressure drop equals more efficiency. I laff daily at dickheads with truck cores who have no comprehension of this. Getting off topic tho... I say bigtime gauge error. Probably both gauges to some degree. Looking at figures... hard to say, but i think its possible they plumbed up bad and it was bleeding during the test. I would think that you would have to have rock bottom minimum 8.5psi with a FMIC on a dyno, and erratic AFR's, to be able to get 145. Do these guys use a fan? This is my only other explanation. No fan to actually cool the front. Instead you have an "interheater" as the heatsoaked core actually raises intake temps and boost value. And fucks up your AFR's as temps sensors go nuts...
