Bernie:

Once you learn that on a turbo car you can still accelerate while
LIFTING the throttle to maintain control and being ahead of the car
instead of behind it, you'll do better.

I think youre driving with a 1 bit resolution on the throttle, instead
of a measured response to what the car -will- do.

Trust me..the BIG super many hundreds more HP turbos than what you
have are hard to drive, not a pea shooter with an upgrade.  ;)

Most issues with driving a challenging car, are the drivers
fault...dont waste any time or money bringing the car to your
level..you rise up to its level.
