Fox, good to see someone else (very few) who understand the difference between work done in time and torque. Wax, I would also recomend polishing the exhaust pipe on the outside. This will help the crystaline structure of the metal become more uniform and able to make the return wave more consistant in volume. WAX, I have talked to reliable sources and have heard some numbers. TJ told me once that he built some engines for customers with $$$ then dyno'ed them. Later those customers claimed that the engines were not all that. He got the engines back with some minor changes made by the customers and upon redynoing them found that with the customers tuning that almost 20hp had been tuned out of the engine. He said its so easy to lose hp through what may seem like a good idea let alone there are very few tuners at the pro level. Most confuse torque,hp with responce. I don't cause I don't even know what they are!
