With the number of engines of various kinds that I have built over the years (too many to remember)...there is one thing that is consistant in the whole bunch....no two are completely alike!
I was once asked to build several 350 cu in Chevy engines...all with the same compression, cam, valves, etc....and the dyno run differences were amazing.
Even with all the same equipment...there was alost a 25 HP difference between the top and bottom of the bunch.
All that this proves to me is...there will be hidden HP in every engine...subject to altitude....temperature...humidity...and every other change in earth position and variance. (maybe even hemisphere?).
I think Loren is both correct and wrong because of this...given the narrowness of his statements.
Sorry man...you are on the right track...but keep an open mind.
Steve Wong chips probably address the advance curves and mixture control...as do others of the after market type...but that's not all they do (depending on the before mentioned variances).
After market chips will almost always pull out better numbers than the factory ones...simply because of the date...the factory ones were designed a long time ago...Wong's chips and the others are designed with time on their side (newer gas...better plugs...etc.).
My $.02 for what it's worth.
