Reading this thread no one has explained the issues with induction kits and atmos dump valves. So here goes. I run a Manifold Air Pressure sensor instead of a MAF due to the ECU I run.
Induction kits. The OE airbox fitted with a decent panel filter is good for 400 bhp. Fitting an induction kit can upset the MAF sensor due to turbulence through the MAF tube. I tried to have my car mapped on the OE ECU with the MAF sensor and the mapper said no due to the eratic readings caused by the turbulent airflow.
VTA dump valves. To calculate the amnount of fuel to inject the ECU uses the MAF to measure the airflow into the engine, Airflow X equates to fuel amount Y. By fitting a VTA dump valve this then dumps air from the induction system, this means that the car is now running rich. As the fuelling is set for airflow X but it is only getting X - VTAout. This rich fuelling can cause bore wash due to excessive fuelling, which can get into the oil and thinning it and could lead to engine destruction.
Unless changing to a MAP sensor stick with the OE airbox and a recirc dump valve.
I hope my explanation helps you decide on what you do.
