Boost Pressure?

[strokinearlyin99]

I got a couple questions here that i was wondering about..
1.Do the Early and Later trucks differ in boost?(Turbo Size)
2.The other day while passing a friend 80+MPH in his "Cummins" with the boost tube delete i threw a Turbo Boost Pressure Code. "Went on for about 30 sec. and went off." What amount of boost causes the light to throw? (I have no gauges yet and wondering.)
Thanks!

PS-That Turbo was Screaming!

Any Help? At All...

22-25psi will throw that code.

If you removed the "red" line, you are now pushing 24-26psi max with your setup. If you put the truck on a dyno, I'd bet dollars to donuts you aren't making any more power. If you ditch the edge and chip the truck, you'll be able to push 24-27psi without removing the line. I doubt you'll hit much higher than that with the 120cc AB injectors.

What if i was to switch to dp tuner and a Beans D66 Turbo?

Same as my statement above. But once you replace your injectors, you will build a lot more boost.

DP is GREAT. You will need to replace your pcm with a late 99-03 pcm. The early 99 pcm isn't that great. The late 99-03 pcm has a different architecture that will build a lot more power.

D66 is a good drop in replacement. You will NOT be able to run injectors larger than stage 2 without damaging this turbo.
