Hi I'm new here and Z's, just looking to buy a one.
The car I'm looking at an 04 car that has had a Nismo cat back performance stainless exhaust system together with a Nismo induction system fitted. Now if I go a long way back to when I use to play with sorry, minis and escorts and the like making these sort of changes required a trip to a rolling road to reset the tuning due to back preseure changes etc. Will this be required with this change or will the ECU cope with it.
Also what sort of power change would this produce and the resulting change on MPG
thanks
