I had a few questions about how to take my car to the next level...
My current set-up is a '97 GS with a Hahn stage 2 kit w/ FMIC, currently running 8psi.
?s 1) How much boost could i run with only upgrading my pistons & rods? 2) With only doing #1, is tuning software a must? 3) Is #1 worth it? or should i go all out at once and also do some BC 272's, ECMlink, Clutch, Flywheel, LSD, bigger injectors, etc? 4) Y did Hahn delete their stage 3-5 kits online? r they even available any more? 5) Is there anything in #3 that I missed for a pretty powerful car? 400+ hp?
