I have a 2001 7.3L Diesel Excursion...
I've upgraded to a 4" turbo-back exhaust, AFE Air Raid filter, and a DiabloSport Revolution chip. DiabloSport estimates 125HP with all mods together and it sure feels like it. By the way, they were GREAT and very patient in letting me try several programs--for FREE. Don't get that kind of service very often--and they didn't even sell me the chip direct!
Since DiabloSport is close to me, I went and had them set up the chip and we tried several different combinations. During the test, the tech disabled the waste gate and the max boost went from 23-24 to 29-31 (very subjective as I was trying to concentrate on the road).
As expected the MAP Sensor detected >24 lbs. or boost and set the SES light.
So the question is this:
I know that I can limit the boost pressure the MAP Sensor sees to
2001 PSD Excursion, 4" Lift, 315's on 17" Weld Evo Velocity-8 chrome wheels, 315-75-17 BFG AT/KO's, SS Westin Tube Steps, 2200 watt sound system, full pillar gauges, AFE Air Raid, DiabloSport Revolution experimental custom EEC chip (120HP) tune, 4" exhaust, clear turn/head lamps, safety brake light, oversize wipers, 2003 SuperDuty turn signal/heated power towing mirrors, billet grill, limo tint, ProComp steering stabilizer and shocks, the list goes on... |

If I understand your question right, you want to know what pressure to regulate the map pressure to. Regulate the map pressure to 21-22psi, then put your boost gauge sensing tube before the regulator or in the intake.
