<p>[QUOTE=&quot;OutlawW900, post: 11682990, member: 326112&quot;]Ok will ask them on Monday to run this test. Today we were monitoring the commanded pressure vs the actual pressure and noticed that they were almost identical until we got up high on the rpms, there was a difference of almost a thousand psi short. Also the truck showed the SPN code 157 active even when truck was off. So on Monday we’ll also check the wiring harness. There’s still a consensus amongst some of the shop guys that it might be electrical. I don’t believe so but we’re running out of mechanical things to do.[/QUOTE]</p><p><br /></p>
