Here's the thread on the OM617 intercooler install:

It was a fabulous job, but somehow he became convinced that power gains would come simply from cooler intake air, and no extra fuel was needed. Also note that his "baseline" included boost pressure below spec (probably 6-8psi) and then while the IC was installed, one of the changes was turning up the boost to spec (~12psi). He felt a big power increase and thought it was from the IC, but it was just from getting the car back to what it was at the factory - IMO. He refused to post any 0-60 data or anything else, which I believe is because it was no faster than the factory performance ratings, lol! All he has to do to make that thing tear up the pavement is adjust the full-load screw. **sigh**
