I think that dealers can definatly detect chipping because they can access your engine management logs from the ECU (I'm no expert at this but the dealer certainly could tell I was chipped when I had my APR - even when switched off). Some dealers care more then others about taking issue with a chipped car. I also think most dealers would notice non-stock downpipes - again - would they care - don't know...

 

Well..........Sorry forgot to add you need the lock out feature activated to not let the dealer find it.................And the piggies are stock.They just basically gut the stock ones. that is why u send in yours. There is a core charge.

 

What is this lock-out feature?
