Me personally am looking to find the sweet spot and would like to know what are mod quality parts to be bolted on without rebuilding the bottom end?

There's a few others as well that are excellent units. Our PCV system vents excess crankcase pressure from blow by into the intake tract just forward of the turbo. Unfortunately, when oil mist gets mixed in with the intake charge it can lower your effective octane from 93 to as low as 89 resulting in detonation. I recommend an OCC even for Stage 1 tunes for this reason.

As far as meth injection is concerned there are two schools of thought. The first is to use meth injection to add an additional safety factor. Turbocharged gasoline applications will always be det limited. Meaning you will reach detonation before you reach the timing limit for maximum torque. Since detonation limits are dependent on fuel, methanol with its high rating helps level the playing field a bit without resorting to extremes like E85. For moderate tunes a 0.6mm nozzle with an 80/20 meth mix will give you a nice safety margin.

The second school of thought is to use the timing increases methanol allows to make more torque and horsepower. Injecting 500cc of the same mix via a 1.0mm nozzle in conjuction with 93 octane fuel gives you an effective octane rating approaching 100. Besides its actual octane rating it further reduces detonation by lower intake charge temperature via evaporative cooling.

Some important things to keep in mind when following the second school of thought. 1) Ensure your methanol injection system includes a failsafe that will automatically cut boost if you run out of methanol or the system detects a malfunction. 2) Methanol is FUEL. Our fuel systems start to max out when injector time hits 7.2 to 7.5ms. What that boils down to is without meth you can hit 235 to ~250 whp on our stock fuel system, depending on the vehicle. Some Mini's do better than others. A lot of thing come into play and need to be data logged and adjusted for but with meth acting as a secondary fuel source you get much more head room for tuning in additional power. So when tuning for power with meth the presence of meth is critical and skimping on your meth kit is not a good idea.

I'm not familiar with 1st Gen dyno charts, but I'd guess that the curve has more effect on torque steer than the peak --- when peak torque occurs at lower RPM's, I'd expect more torque steer. I've heard from other high power 2nd gen owners that torque steer is a significant problem. Not so much from 1st gen, even when, like you, they have 300+ numbers. Does your chart peak near rev limit? My torque peaks around 4400.
