This is my 2011 Buick Regal CXL Turbo in Granite Grey Metallic.
The initial release of the 2011 Buick Regal CXL Turbo was built in Germany at the Opel Insignia plant that the car is based on.
Later cars were built in Canada. Mine was built in Germany, while my tuners is from Canada.
It uses a LHU 2.0 Ecotec Turbo engine rated at 220hp
The engine is essentially a de-tuned LNF 2.0 Ecotec engine, except the LHU is full flex fuel capable, any blend of E85 will work in the car.
The more powerful LNF engine was rated at 260 hp from the factory, but with a tune and bolt ons is capable of 300-330whp.
My tuner, Vince @ Trifecta sent me a dynograph of his same 2011 Regal CXL Turbo and it made 262 whp / 284 wtq with his Trifecta tune.
I now have a Trifecta tune, but with his newest more aggressive tune from above.
I have not had the car re-tuned since any mods I have done.
My current plans are a new 02 housing piece and a ZZP EFR hybrid turbo that is a straight bolt on and capable of 500 whp on a LNF engine.
After looking over the stock components of the LHU motor, it seems that Buick decided to downsize parts of the turbo system as opposed to LNF parts.
