7.3 feels like it runs out of steam.....
Well I have tried to research what I am experiencing with my 2002 F-350 and I can't find anything so here goes.....
My truck has the following mods:
-Edge w/ Attitude.
-full 4" exhaust
-EBPV delete with valve removed in exhaust side
-Built automatic trans with shift kit, Suncoast extreme duty interals, Suncoast billet torque converter.
For the past several months now I have noticed that whenever I need to really lay on the throttle as the RPM's climb the truck seems to run out of steam. The revs keep climbing and black smoke keeps dumping but the power just isn't there like it once was.
I watch my stand alone boost gauge (not the Edge's) and the boost will NEVER climb past 17-18 psi even on the "extreme" setting. I want to say that I used to see 22-23 but don't quote me on that. 17-18 just seems low to me.
What I can best compare the feeling to is valve float. I have built many high revving drag car motors so I am familiar with the feeling....and while I am sure this is not the case with a 112k on the clock , that is what it feels like.
So what do you guys think it could be??
I am thinking about pulling the IPR valve tomorrow and cleaning it up to see if that helps any.
Anyway, I look forward to seeing what the 7.3 guru's in here have in mind. I have intentions for some much more serious mods here soon....but I don't want to mask a potential problem that needs to be dealt with up front.
