I've seen and talked to '311' a few times at various events in the past year and his car was not chipped. Both of the events (dyno day and APR BBQ) involved highway driving and I can say that his car was not chipped.
That car has over 100K on it already, so I'd be looking at preventative maint. first and foremost. Wheel bearings, control arms, tie rod ends, diverter valves, sensors, filters, etc should all be checked and replaced as necessary.
Chipping the car may or may not cut those turbos lives short. I know people with 150K miles with their chips and no problems, but I also know people whos turbos blew at 30K on stock software. You will definetly want to pressure test the car before doing anything else.
