Although Crawford Performance's history is rich with successful engine tuning, we no longer offer custom engine tuning service. If you'd like a reference for one of the best tuners in the industry, check out Church Automotive Tuning in Los Angeles.
We were responsible for the custom tuning of our 850hp orange 2008 STI Time-Attack Champion "Tony" (acclaimed as the world’s fastest STI in its day) and Ken Block's Gymkhana 1 & 2 STIs. Not only did Tony win races, it ran multiple consecutive races on the same engine.
The longevity of an engine 95% of the time is due to the tune. Even titanium forged rods will break if your tune is off. Off the shelf tuning maps (like a Stage 1 map that comes on a plug-and-play device) are created for world-wide use. They do not take variables into like climate, altitude, octane variations, or slight equipment variations. We strongly suggest using base/stage maps only during a temporary/break-in period for performance modifications. We have replaced many blown engines that were running a Stage 1 map long-term.
There is a wide-spread belief that EJ's blow up because they are prone to ring-land and rod-bearing failure. It is not the components themselves that cause engine failure; it is pre-detonation which is caused by a faulty mixture of fuel, spark, and oxygen, which all can be properly tweaked by an expert tuner. Keep your engine alive by using base/stage maps with caution, and book yourself a custom tune with a reputable and experienced tuner ASAP like Church Automotive Tuning.
