Is it safe to run on stock 02 3500 with 6 speed straight piped?

 

..................U betcha., mines been on since October 03....I tow 12,000 lbs with mine....kim............

 

mine stays on high even when towing comes off for smog

 

Last week, I tried the high setting & had poor results. Climbing mountain pass w/ a 3000# camper was constantly dropping a gear. Put it back to the lowest power setting & it pulled well. Just my experience. Obviously, others have had good results. Try it, won't hurt.

 

I would not go pedal to the metal for long without a pyro gauge.

 

On hills I have to back off according to the egt readings while. Towing

 

X2 on backing off when towing due to EGT.

 

I can't seem to get mine to go over 1150-1200 even when towing 12k, and lugging it. (Starting to wonder if my Autometer pyro gauge/sensor is bad).

How much boost do you guys see?
Mine spikes past 35psi, then settles back to ~33/34 and then holds there. Makes same boost with the box unplugged too, just takes a lot longer to get there.

 

I am seeing about the same boost as you, but both my boys truck and mine will when towing go past 1200 if we do not let off the pedal. when not towing I would find it hard to see those numbers maybe impossible.. check it out may be an error in the sending unit.

 

Sounds about right. I run my EZ on the middle setting, but that's because I have 100hp injectors. Even with the injectors my egt's generally stay under control. There is a lot to be said for adequate air delivery. Probably the reason you don't have a problem with it is that you have the boost elbow in, and don't have any boost of preturbo exhaust leaks. Enough air flow= lower egts.

Are you getting 35 at the manifold or at the turbo? I understand there is about 3 psi drop from the IC.

 

That is 35psi at the manifold.

 

Wow, no wonder. My boost elbow is only giving me 32 at the manifold. Even with more fueling and less boost, I'm making pretty manageable egt's, so your's fueling 60hp less, and +-3psi more. Makes me want to poke the hole a little bigger on my boost elbow.

 

Throw that piece of junk in the trash mine just cost me $1800 in damages only running it on level one. You will trash your injectors with a pressure box such as the EZ.

 

He's talking about a VP44 truck.
