you'll have many more problems with Lambos than with the Lingenfelter. The reason they don't run crazy amounts of boost on their cars is because of the reliability issue. I believe they are running 8-10 lbs. on the 427TTs. Without altering the boost, Lingenfelter offers a 2 year/24,000 mile warranty. If you up the boost, you'll be pushing over 900hp at the crank, but without your warranty.
