One of the great things with Eurocharged is you can tell them what your modification priorities are and they will deliver a semi-custom engineered solution. To ensure synergy and consistency, I got the 65mm pulley, ECU and TCU tunes done simultaneously. For the outcome goals, I specified 1) Driveability, 2) Durability and 3) Performance in that order. I told them this car would never be raced - so, they delivered what I requested and I am totally happy with the 6,200 rpm redline and that it autoshifts at redline with no bouncing. Even with placing performance last, I can't beeeleeeve how fast it is. This is truly a great car.
