Has to be the mods, and Tuning from Bama chips, and I also maintenance the heck out of it, Royal purple in everything, Fuel filter every 20K.....ECT...
Nothing "special" done to the motor everything is listed in the mods you read...
I dont think the bored TB and hand "massaged upper intake" do any thing on a stock internal motor...
Don't know, but ask SAL and Gary D last time, they needed gas, I still had plenty...
AND this time home ask Vic V, He needed gas 4 times and every time I still had plenty to go...
AND I also checked my speedo with 2 GPS's and it was dead on......
