I cannot tell you how many times, on EVERY car forum Ive visited, people get in trouble with cars that arent running properly- so they decide to do the old 'fix+upgrade' thing.


For master engine builder, tuners, etc- maybe this works. But now you have a 'configuration' that nobody really knows.


I think looking at the ECU/tune is a good idea at this point....


here's hoping there werent other 'known' (but only to the seller) issues that you couldnt detect in the 30 mile drive...
