Tuned car, part change concerns
Hello everyone! I'm not sure I'm in the right place with this thread, but my car is tuned. It had a MAP cast manifold and an MAP open dump. I'm changing to a tubular mani and looking at a widemouth DP to quiet the car up. stock turbo, 93oct tune. is that enough change to worry about a retune? also, whats a target AFR? putting a wideband on while it's apart so I can monitor if it acts up. Thanks!
