I'm wanting to lean out my air/fuel mixture in lower rpm's with my supercharger setup. It's running a bit rich right now. Would a VAFC be a good way to go? A little background info. Jackson Racing Supercharger on a D16Y8 (stock internals). There is absolutely no one within 8 hours who can dyno tune. And I'm new to any type of tuning. So I'm thinking either of going with a P28 and using a VAFC for some self tuning or either going with a chipped P28 from Phearable.net and using their recommended basemap for a supercharger setup. Would a chipped ecu be able to do a good enough job for my car or should I attempt tuning myself? I'm on a sub $300 budget. The car runs fine and dependable now but I want to get the most out of my setup.
