Been researching the turbo systems on the M3 cars. Seems like most aren't that bulletproof. The cars run fine, but tend to have their idiosyncrasies. (i.e. pinging under load.) But it seems to be a software issue.
I like the DINAN set-up though it's about $3k more. At least Dinan has built the system right.
Anyone else with a take on the turbo systems? How about the Dinan ones. Are they are completely trouble free as promised?
