Just a quicky.
I've modified a few previous car now to around 300bhp and they have all been different in the respect of mapping specifically for modifications.
As an example I bought a standard Focus ST225, got it mapped on the day I bought it by a company called Pumabuild (their own map) then bit by bit I added firstly a 3" cat back system, then a month or two later a CAIS, followed next month by an uprated intercooler and sports cat downpipe. At no point was the original map changed and on a rolling road the car produced 310bhp and 350lb/ft with as perfect power/boost/fueling graphs as you could possibly get. The very clever ECU in the Focus adjusted everything to optimum based on the readings from all the sensors.
Then... lets take my 2006 Impreza, every major modification you added had to have the map tweaked to suit or you got all sorts of overboosting, fuelling and other problems. You actually had to drive it off boost to the mappers to have it tweaked.
So the Audi S3... on Saturday I'm getting it shark stage one mapped by Brodster. It's bog standard just now but lets say in a months time I want to add an intake system, then the following month I want to add a turbo back exhaust. Can I safely add these things without having to go back and immediately have it mapped again? Will the ECU account for these and adjust what it needs to to run the car safely now the whole system is far more free flowing?
Cheers!
