So, I'm loving my new FXT quite a bit.
The only thing I am surprised about is the amount of turbo lag from a stock, small, ball bearing turbo on a 2.5. What's up with that?
I know I spool slower at altitude, (6500 feet), but punching it from idle at a stop, it seems to take 1-2 seconds to get into boost. I know I could powerbrake and stall up the converter, but I also know that is a great way to make sure your 4EAT lives a short life.
I suspect that this is part of the whole "lets detune the crap out of the FXT so it doesn't take away WRX sales" deal, as this thing spools slow- slower than auto DSM's.
I don't want to dive right in and replace the Up pipe on a brand new car, but I am thinking about playing with tuning to basically 100% close the wastegate off idle until the turbo spools- I would guess the stock duty cycle doesn't do this.
