My old ST made a lot less torque running stage 3 than Superchips graph shows, power curve looked similar but down like 100Nm with the torque. But with the dyno lottery it gave 20 bhp difference on different dynos on consecutive weekends Sticking to wheel horsepower is a much better comparison - some dyno's run a coast-down to estimate transmission losses, others just apply an arbritary correction figure.
Generally as the gear ratios get higher and spread out further the car will feel like it's pulling for longer as it takes more time to reach peak rpms and you feel the boost for longer. ST's always tend to feel really punchy around 2500-4500 rpm, which is why power figures don't tell the whole story - you need to consider the torque curve too.
I always just found with Bluefin, Mountune and Dreamscience maps as well it was very difficult to get away quickly without losing traction, trying to get shifting in the wet and performance seemed to drop off sharply after that - the Collins maps feel very linear, progressive in comparison and tractable in comparison.
Ok so after everything that has been said I am considering just buying a full blown RS; however I still do like the idea if a highly modified focus ST. What's the cheapest way to bring the car up to around 300bhp?
