Hmmmm...I think that it is highly possible for the PCM to be the culprit in this dilemma, but until we can get someone to crack the hex on both a 99 and a 00-01 PCM, we won't really know if the tables and modifiers are truly that different. There are many other examples of this same phenomena with other performance cars....in fact, the owners of 01 Lightnings are complaining that their trucks don't respond like a 99-00 to the same mods. Part of that stems from the upgrades that Ford made on the 01...bigger MAF, different lower intake, gear change, etc...and accordingly, the tune for the PCM is different. Granted, the Viper did not experience any radical departures in terms of engineering from 98-01...but, there is zero chance that a minute cam profile change would have the impact suggested.
Now...onto the underlying smack found within this post...BLS, you are the unknown element in this contest. If you decide to show up, then we find out how good you, well.. at least your checkbook, are at the performance game. If you don't show up, everybody knows that you were just trolling and the 77 LTD you really drive couldn't make the trip out of your driveway..much less to Texas.
I just wanted to let you know that I believe in you man...if you put your mind to it, anything is possible....you keep reaching for the stars and chasing those rainbows....seize the day BLS.
Almost forgot....here's a riddle for you....What is a Pontiac, powered by Buick, and driven by Ford that is capable of dragging your Samurai down the track??? Hint..it too has six pistons and a BIG turbo....for the answer, come to Texas in late October. Adios muchacho.
