What should the boost gauge read when you're running down the road at 55MPH in a stock 2000Ram 2500 with no load? With Load?

 

I'd say around 18psi running at 55mph. With a load it just depends on what the rpm's are doing. Boost pressures are all over the place so it's hard to say exactly what you would be at.

 

no load level ground can go from 6-10psi. . .loaded on the same stretch can put you around 15-18 depending on load.

for me. unloaded on level road running 70 will put me around 10psi. . .with 5K in the bed I'll see about 14, 8K in a trailer is about 15-16

 

drew is pretty close to mine,unloaded at 70 it stay around 5-6psi,when im loaded or towring it can climb to 12-15,but when accelerating to get on higway it goes 20-30 and 45 is only when i really mash on it

but speaking of this,the overboost code only show sometime when i go around 40+,when im fooling near 30-35 it didnt show to defuel my beast
