Had my car on the dyno at Cobb Surgeline a month ago. Running the Cobb stage 1 map on 92 octane I put down a modest 192/242. Can't say enough about the great customer service! They even took the time to data log and review it. Thanks Cobb Surgeline. I'm planning on buying a Cobb intercooler next next month and running the stage 2 map. In the meantime I switched back to stock map and filled up on 87 octane...just for an interesting experiment and to increase the dramatic effect of going to stage 2. Yes, I'm bored in rainy Portland and need something to work on! Wow - all I can say is SUCKS. It really makes me appreciate the Cobb tune and can hardly wait for my new intercooler.
