Disclaimer:

The use of a SMBC or MBC is very safe in many applications. You must research and evaluate the use of these devices on your own model/year/engine etc. The MBC will work well where any MBC could be safely used. When increasing boost; the engine must be in good mechanical condition, a true synthetic oil and good filters should be used, plugs must be in good shape and the heat range might need to be changed (cooler), premium fuel must be used, keep fuel injectors and combustion chambers clean (Techron Concentrate suggested), as a rule of thumb - one needs to have a low restriction intake and exhaust when increasing boost pressures, it might be foolish to increase boost pressures with a stock intake and exhaust setup.

Lean air fuel mixtures at higher boost pressures and air flows can lead to knocking and damage. If you hear any knocking, get off the throttle and reduce boost immediately. Learn what can be done with your vehicle. A MBC may be all that you need for more power, but some applications would require larger injectors or greater fuel pressures. Study and find out what works and what does not. You may need to install a fuel-air meter to monitor the AF ratios. Some well known applications need none of that, but you need to know these details for your self.

You are your own warranty. We are not responsible for what happens to your engine or drive train when increasing boost pressure.
