Just wondering when you get a reflash what happens if you get any det? Does it retard timeing like the stock ecu would?

 

Yes it still does

 

Ok that explains why my car was feeling a little laggy probly..

 

There are a lot of other possible explanations

Can you please describe in more detail your exact mods and how the car is feeling and reacting ?

A qucik diagnostic for detonation is to add some race gas and reset the ecu
