All,
New to the thread and to Engine Monitoring systems.
Just hooked up an Insight CTS2 and started looking at numbers to try and find a clue as to my potential issue.
The rig is an 06, 2WD Super Duty Longbed with 5-speed automatic transmition (with Tow Haul mode which doesn't seem to lock like it used to / different concern). ~130k miles
I have done all recommended upgrades except the Head Bolts (Waiting for the next explosion to pay for that upgrade).
The only After market hardware is a Bullet Proof Diesel Oil Cooler system with relocated oil Filter and BPD EGT cooler (bigger water coolant tubes).
I did have a BPD Water pump put in too.
The issue.
I can't get more than 5-10psi boost until I hit 2000 RPM or so.
Very difficult to get moving from a complete stop.
I used to be able to Power Break and get 25psi on the dash mounted Boost Indicator.
I could give it 3/4 Throttle, Full Breaks, Not Moving and spool up the turbo to at least 25psi.
When towing a trailer, it's useful for crossing highways to be full power before letting off the break.
I'm on my 4th Turbo. Maybe I'm hard on turbo's, but I doubt it.
The factory turbo shredded and launched metal parts into the exhaust system (23k miles). Ford said it was "known issue"
The Second turbo worked well until about 65k miles when the VGT would get stock closed (Over Boosting).
The Third turbo had the this problem (low boost) so ford replaced it with my now fourth turbo.
Ford replaced the Piston thingy, after putting the 4th turbo didn't fix the problem.
still have the problem.
Now I have my CTS2 Insight and am looking for what to check and look for.
I have been reading your threads, and checking my numbers, but decided to just ask you guys your thoughts.
Mass Air Flow maxes out around 340 under full load and full throttle. Normal or possible intake restriction?
Exhaust Back Pressure is 2psi to 15psi (Idle to Max Power). Possible Exhaust leaks or restrictions?
Variable Geometric Turbo duty cycle is 65-70% at Idle when warmed up (180f Coolant and Oil temp).
VGT duty Cycle is around 20% at full load, full power
Note: It is rare for me to see 28 pounds of boost these days, unless I'm towing up-hill with a 30 minute warm up.
Manifold Air Pressure appears to match my factory boost Gauge (+15psi or so for Sea Level pressure).
Engine Load is 25% at Idle in neutral (no A/C, No Fans, No Stereo).
Engine Load is 35% when in Drive, stopped, Idle (WITH A/C, Fans, Stereo on)
Engine load goes to 100% Real Easy, like way before I hit 15psi on the Boost Gauge.
I do not have the Exhaust Gas Temp sensor installed so I don't know what's going on there.
Not sure if any of these are indicators, or if they are even within tolerance.
Any advice on what to look for next, would be helpful.
Thanks,
