Lt. Dan, do you have an intercooler with those boost numbers or is that with the stock Y-pipe? Going to do an intercooler after I do E-fuel. I'm looking at the csf 6028 or 6013. Leaning towards the 6028 for the bar and plate construction instead of tube and fin.
Was it a mistake to go for the 6+6 anti-surge 66/88 wheel?
I had the stock y-pipe at the time when I made 38psi, but my turbo is severely worn out right now, and after intercooler, I struggle to make 25psi now. So I have a DieselSite Wicked Turbo on the way.
When I intercooled it, I noticed a 3-4psi drop in boost, which was a little disappointing, but, I was able to push the truck harder, for longer periods of time because of my drop in EGT's, thus I was able to make more power, even with less boost.
The stock turbo is only "good" for 25-30psi, anything after that and its a crap shoot on when it will die. Could be immediately, could be years. Mine lasted almost 3 years and 30,000 miles and its pretty much toast, but over that 3 years I noticed my boost levels dropping slowly over time.
As far as intercooler, I would recommend trying to find a stock aluminum tank 7.3 intercooler, they can be had for $100-150, and they work great. That or a 6.0 intercooler. They are both great.
The 6+6 anti surge wheel wasn't a bad idea, it'll serve you well for a while.
