One of our list-members makes a stiffer spring, with instructions on how to
defeat the overboost fuel pump cutoff @ 1.5 bar. If your CD is an auto, you
need to be careful with this kinda mod because your tranny may not be up to
it...

I intend to have a custom made 2.5 inch cat back system done in the next few
months. Any competent shop can do it for you. I also plan on replacing the
cat with a hi flow model that JC Whitney has on sale for 84.00.
