By Are Wicked Wheels worth it?
Wicked wheel is a waste of money. In general, very few “special” compressor wheels are worth a damn. Any who, the stock turbo limitation is in the turbine. Put a bigger turbine wheel on the stock turbo and the stock compressor wheel will give you 600hp.
Is the LB7 really that bad?
The one issue the LB7 is best (or worst) known for are the fuel injectors. There are several causes of the failures, and the issues were so common, GM covered the injectors with a special extended warranty for 200,000 miles or 7 years after the vehicle was placed in service.
Was the LB7 a good motor?
Out in the real-world, it went about its work quietly and efficiently, with many ¾-ton Chevy and GMC HD owners reporting fuel economy numbers as high as 22 mpg on the highway. Over time, and aside from the infamous fuel injector issues, the LB7 proved to be one of the most reliable diesel engines ever produced.
What is wrong with LB7?
One of the most common LB7 Duramax problems is leaking O-rings on the Fuel Filter Housing. As these trucks continue to get older, the original o-rings can deteriorate over time. They’re also susceptible to normal wear and tear. A leaking o-ring not only results in a fuel leak, but air can also enter the fuel system.

Should I delete my EBPV?
Removing the EBPV will give a minimal increase in air flow, but mostly, it gets rid of the cold weather operation of the valve. I’ve left mine in tact for helping to warm the truck during the winter months. Since your location normally doesn’t get that cold, I wouldn’t see it as a big gain either way.
