Lyndon is a good guy - call him and ask. He also has a website that lists all the stuff he works on.
However, it is not the same reflash that the 'big guys sell'... Kennedy does his own (in-house), Heath has his flashed to his specs, KOJO (member here) does his own to his specs and will do custom work... The only one of the 'big guys' who uses Lyndon Wester's tunes is Walt at SSDiesel - he puts a new sticker on them and sells them as his.
Which one is best? LOL... beauty is in the eye of the beerholder, right? Most everyone I know just loves what they have, and claims it is the best. Nobody I know has taken the same truck and swapped out the various reflashes and dyno-tested them all under the same configuration.
Which means that everyone's opinions are just that... keep that in mind.
