20lbs would probably be the max on a stock 4d55 or 4d56.

You'll get much better responses to your posts if you turn off your "CAPS LOCK". It is considered shouting on most forums, and is poor etiquette.
Thanks

No offense taken or meant, figured you didn't know: lots of folks don't. And your English is fine. Punctuation? Well, I'm a teacher, so maybe I'm just picky? <img src="/forums/images/graemlins/lol.gif" alt="" /> Wasting time with a Paj? Well, in that case I've been wasting time for the last 13 years. Heheh! If its a waste of time, I can't think of a better way to waste it! <img src="/forums/images/graemlins/cheers.gif" alt="" />

I would not increase the boost on ANY TD by more than 10% of the spec.
Even then you will be well advised to fit an EGT gauge to keep an eye on combustion temperatures.
Don't ascribe to malice anything that can be adequately explained as stupidity!

Well at 17PSI boost max currently. Running 80-100 KPH i sit around 700 degrees farenthieght if i pull a big hill i hit around 1000-1100 degrees i was always taught anything under 1200 degrees was good and if you are pulling a sled or something
1500-1800 was ok for that short duration i have a 2001 F250 in the US i use for sled pulls and stoplight racing
