LS6 corvette engine I fixed for a friend of mine. Engine is pro charged and the tuning had some issues. As you can see 2 cracked pistons and 1 bent rod. Did a partial rebuild to get it up and running. Its getting a new tune next week. #ls #corvette #c5z06 #procharged #chevy #ls6 #bmw #n54 #335i #engine #rebuild #detonation #blown

We provide 335i N54 DME repair. 2007 and some 2008 models have an MSD80 DME which is prone to mosfet failure. This causes your engine to go into limp mode and run on only 3 cylinders. When one mosfet fails, it takes out a bank of 3 cylinders, 1-3 or 4-6. It will also burn out the coil packs on those cylinders. Contact us for more details!
