No. Its the stock to S1 that is the massive jump . and probably the best bang for the buck . Stage 2 will need an intercooler and downpipe with maybe 20-30 bhp depending on the car.

I have a high flow catted downpipe already installed together with the stock exhaust but am still running on Stage 1. Am afraid that Stage 2 will make the car undrivable at low speeds and low rpms.

Why would that happen though ? You need an intercooler too for Stage 2

I heard that it's too much backpressure. Makes the car extremely jerky at slow speeds. It's a 320i G20 though.. so no xHP yet to do a TCU tune.
