Get RMS to fit water injection will cost ya a bit over a grand but if your car is tuned with the water injection running you can gain ~40nm torque up top purely because the car can be tuned with like 10-15 degrees more timing because the air charge is cooler. Also provides more saftey for thrashing on hot days. Dont overlook water injection... WW2 fighters had it, all
WRC cars have it.
