I agree, I think you should also pick up an AFR gauge so you can monitor how it is running. The kit has a bung already in the downpipe, so installation should be super easy. Better to be safe than sorry! My kit runs stoich when cruising and driving normally, but when you're on boost it dumps fuel, like 10 AFR. Always good to know what's going on in your engine!
