Like stock, but better
The Evo 9 is a good car out of the box, but with some very small little tweaks, and not much cash outlay, it can go from good to being much better, while still looking 100% stock.
Here is a good example:
2006 Evolution SE
Base numbers 100% stock from the showroom floor:
234whp / 230wtq
Then with just the addition of:
GST Boost assembly (100% stock appearing)
GST Custom dyno tune
266whp / 264wtq
Peak gains of: 32whp / 34wtq
