I may be swapping my AMS intake for the stock intake or another that allows for a full size battery. My car has been tuned with these mods: the intake, full exhaust (with test pipe), bigger IC (and upper/lower pipes), Tial Q (recirculating), Grimmspeed BCS. If I do change the intake will resetting the ECU be fine?


I'm also wondering if I swap the test pipe for a high flow cat if I'll need a tune right away, that isn't as important currently though.


Thanks.

 

You will most likely need to recliberate your maf back to the stock intake settings, you can paste that table in from your stock map.

you should reset your ecu if you don't plan returned though, this will clear out your fuel trims and give the ecu a chance to compensate for the intake change.

I would play the test pipe change by ear.

 

You should be ok. You can reset the fuel trims and just see what if any changes in afr
