Due to getting lots of private emails about this and doing a lot of checking up and research here is some background

[*]Cars Work History

Owner has a well known shop install a supercharger.

He then takes it for a custom dyno tune at this Speedinc in 2005.

After the lousy tune was done the engine has severe problems.
Speedinc ( also known as LS1speed) talks the owner into a new engine in late 2005.

Shop does not have engine done ( car sitting all that time at that shop) until late March 2006)

Cost over $9,000, including another custom tune being paid again

Included in charging him when they took the radiator out ( keep in mind this is a 2004 and work being done in 2005) they claim it went bad and required a new one, also claimed starter went bad and charged for another one.

Owner is told not to drive car more then cruising speed for couple thousand miles.

Within 100 miles engine seizes up result of very low oil pressure of only 9 PSI.

Has car hauled back to that shop and is told to pay for a new engine, owner refuses and shop demands money to release car, including costs of storing the car at that shop while engine was blown.

Owner has his lawyer contact shop and they release car.

Owner has engine torn down to find new bearing on new crank cooked within that 100 miles car was driven.

Owner claims they never gace him back the old engine and most of its parts.

Owner has engine redone, engine runs like crap, that is when we were contacted and having owner purchase a OBD-II scanner and doing a short drive is when we can see how bad the tune was.
