My Rig below is having trouble pulling my 39' foot 13k keystone raptor toy hauler. My pyrometer is on the driver side right before the up pipe. On really small hills I'm having to back off the throttle due to EGT creeping up into high 1300 range. I don't seem to see more than about 15 psi of boost by Edge CTS.
Can't afford a 38r so I will also be ordering a hydra, WW2 from diesel site or riffraff billet wheel, turbo master wastegate, non-ebpv pedastal and outlet from diesel-orings, dorman up pipes (to eliminate any possibility of leaks - lower EGT). I'm considering a 1.0 exhaust housing but worried it will have an affect on the bottom end with a WW2.
and Max a/c control (b/c its cheap and live in hot as hell texas).
Also I need a new air filter so I'll try riffraff 6637 w pre-filter
My rig - 1999.5 CC LB dually 7.3 with 4" mrbp Stainless Turbo-Back Magnaflow Exhaust, 6.0L Trans. Cooler, Foil MOD, CCV Mod, AMSOIL DIY Intake, ATS Ported Turbo Housing, Edge CTS Insight, HPX, Mag-Hytec Trans & Diff Cover, BTS V/B. A fass fuel system and regulated return w bowl delete is waiting to be put in.
by the way 6637 at riffraff are only 28.99
So you're gonna spend several hundred all the misc stuff and it really won't fix your problem.
The 7.3 up-pipes leak, when mine started to go, my EGTs started to rise. Really IMHO, spend the $$ and do it right the 1st time.
IF you're dead set on the dormans, then so be it, but I will be getting IH bellowed uppipes IF I stay w/ the 38R.
Stock you should see above 15psi but w/ a tuner you should be way above that. I saw 30+ all day long when I ran both my diablo and TS.
IMHO, I'd keep it simple. If you have to DD, get some SB chevy donuts to fix the leak for now. SAVE up the few extra hundred, get the 38R, you maybe even might be able to find one used as someone upgrades.
I'm looking at going w/ compounds when I go back to a 7.3 but IF I was to stay w/ stock or small singles, I'd use IH up-pipes a 38R and call it good.
Great response and most importantly, reliable if you keep boost #'s @ 40lbs or less.
OH, check your HPOP orings, @ 75K my HPOP orings were leaking bad. dieselorings has a great price and the service is top notch.
Fix your boost leak first, get some quality "custom" tunes and start there.
Good luck.
