Once this car is repaired, I hope cobb comes up with the new map since as long as this car has the turbo back exhaust on it, you need to run the cobb map for the 02 sensor in order for the ecu to work properly. The engine has not been torn down yet, took it from the dealer and brought it to my mechanic. The engine is burning approx 1 quart of oil a week and is running extremely rough. ( missing cylinder 4 ) There is no odd noises coming from the engine whatsoever, I hope this isnt a mint to repair! I guess first step here is to pull the head! This car was run at HIGH rpms. The dealer will not look at anything on this car now warranty related.
Should not be a surprise, as any time you modify the powertrain (or anything) you risk voiding the warranty.
