Would agree and have similar thoughts about the PS2.

I specifically only drive Canyons (in CA) and expressed this both to the shop and tuner with end results in mind. However, after many map revisions, the PS2 stills spools very late (close to 5K) and then goes off like a rocket. Below 5K, the car feels dead. This is not well suited to canyon driving.

Yes - I have changed driving style to suit, but still, keeping the car in high revs is challenging at times, particularly on technical, lower speed roads. The car almost feels 'ON' or 'OFF'.

Knowing what I know now, I would say the PS2 suits the guys looking for fast drag times and more open/sweeper roads & tracks. Keeping the PS2 in that higher rev range to exploit the turbo can be challenging on technical roads.

I have asked Wedge to see if we can spool earlier, but have been advised to just drive the car in higher RPM......

Cheers
Your PS2 spool at about 5k? At what rpm do you go WOT when it spools at 5k?

I have a PS2, self tuned, and in 3rd if I go WOT at 3100 rpm I'm at 23#, which is my target, by 4300 rpm. In 4th if I go WOT at 2k I'm at 23# by 3500. Even from a 2k roll in 5th gear I'm at 23# by 3300. I think your issue is your tune NOT the PS2.

I really like the PS2, but having said that I think I've maxed out what I can (reliably & efficiently) get from it and am leaning towards a PS3 swap probably within the next 6 month.
