With a set of RV275's and an Edge EZ, stock everything else, my '01 Dyno's 335hp/852tq, it will pull hard. I would say about $1000.00 and includes pyro and boost gauges. I did the upgrade at 36,000 miles, it now has 220,000. I have never really wanted anymore, it is too dependable at this level.

The trucks pull great stock. My benchmark is to not be the poor guy in the right lane doing 35mph going up to the Eisenhower tunnels on I-70 at max GCVWR.
