Wake up that sluggish 20v! This package picks up where our Stage 1 tuning left off. Gone are the flow restrictions of the stock MAF. We have cnc machined a new billet piece that allows you to install your stock sensor into it, with a vastly improved flow range, while retaining very precise metering abilities. Abolutely no wiring changes required for this upgrade.
This chipset is a direct upgrade for the stock 7A engine. Substantial power gains in the midrange and on the upper revs which were previously chocked down breathing through the tiny stock MAF. This is the exact same MAF housing we use in our 7A turbo kits, and is by no means maxxed out with a stock 7A. This means you will have the ability to take advantage of any engine mods done to your car and still let it all breath and run properly if you have a stroker kit, or aftermarket cams, exhaust, etc.
This kit includes the new mass airflow sensor housing, high-flow direct fit silicone inlet hose.
An HKS Shallow, high flow filter element (which is a direct, precision fit on our Billet MAF housing), is an optional item. The MAF inlet is 80mm and will accept many common aftermarket filters.
We have software for both the early (2 connector) and the later (4-connector) ECU. Select your ECU type at the bottom before checkout.
- We now only ship chips which can be installed by the user or an ECU specialist, we no longer offer the service of shipping in ECU's and modifying them.
- The factory airbox is not compatible with this modification as it is very restrictive, we recommend running the HKS air filter we list above, this provides optimal flow and filtering for the new airflow capabilities of this MAF and chipset.
