Chappel..
He is Mark Chappel and the man who OWNS TST and the person who has done all the dyno work to support his suggested power levels on these trucks.I am very certain he was doing this LONG before Dave Goerand and I do realize that Mr.G's tranny's are the real deal.So take a chill pill gang.......Andy

 

speaking from experience i cut my fuel plate to a flat profile. i messed my stock tranny up in a matter of minutes. now i drive it like an old man to try and make the trans last till tax time. oops!
