Why not put in the boost elbow?
It comes with instructions, that are simple. I have had my EZ on for 6mo or so now. I put the elbow on and have not taken it off. I know Edge says it is not necessary, but why not use it? Higher boost=Lower EGT's, which is always good, also higher boost=more air=more power.
P. S. In all my experiences with Dodge Cummins pickups, the EZ is the quickest, easiest, and best mod I have ever added. I know others (i. e. Comp) will give you more, but it would also cost me a lot more (clutch, turbo, exhaust, intake, etc. ). I have a set of gauges, but they are the big 2. 5", I hooked up the pyro after installing the EZ, and could not get over 1000 deg. I took the big ugly gauge off, and would not hesitate to run an EZ with out gauges on any HX35 equipped truck. Edge hit a homerun with the EZ. When I get more money I will add a set of injectors, 4" exhaust, new gauges, southbend clutch, and a different air cleaner, but the EZ is staying.
