Engine/Transmission (1998.5 - 2002) Stock Boost Pressure

[madmanmanick]

Does anybody know the max boost pressure of a stock turbo on a 2001 CTD with an automatic transmission?

My 2001 HO 6 speed made 20 psi stock.

I thought they were rated up to 35?! When I put my TST on, it would read 42max, and that lasted almost a year1/2,R. I. P. :-laf

We have the same truck, once I got a boost gauge on it I saw I was making about 15-18lbs stock ( I think, was a long time ago). Then I got a a superchip and could make 20-22lbs. I think the HY-35 9cm ( the stock turbo on our auto trucks) are only good for about 25-30lbs and then they are just pushing hot air. A good, cheap upgrade is to get a HX-35 with a 12cm exhaust housing. They were on the manual trucks of the 01 and 02, but I think they were on just about every truck from 94-00. Once I swapped turbos I was getting 25-28lbs. I added 100hp injestors and a boost fitting and I could tap out the 35lbs guage, but i was also getting pretty hot too. Later I sold the chip and bought a TST pm3, I also got a 50 lbs gauge. I was hitting 47lbs but you could tell it wasn't really pulling hard in the top end. HX-35 are only good for about 30-35lbs. I got a PDR HX-40 and its waste gated to 40lbs, but you can tell it pulls a lot better. Although you really need enough fuel to spin it. I sold my injectors so I just have stock injectors and the TST chip, I can only make 30lbs and the truck feels way over turbo'd.

If i remember right, when the ECM sees 20 lbs. of boost it defuels. That is why a stock truck only makes 20 lbs. The boost foolers intercept the signal from the map sensor and buffer it, that way the computer does not see a correct boost number and therefore does not cut back on fuel. Randy

This is exactly what my truck did before mods... . I had one of those stupid Bully Dog J-Hooks and what a complete waste of time and money. It jumped to 23PSI and did not give anymore power... . sad thing is,the Butt-O-Meter was telling me the darned thing slowed down after the Hook. When I bought my truck last year all i heard about was Bully Dog this and BD that. I joined TDR and I rarely see a sig that has Bully Dog upgrades... . wonder why?My Torque Dog module does alright I guess but for the money ,the Smarty does much more.
