I would think a 1.8t with the mods you listed would pull a stock wrx fairly hard from a roll. Just a chip on those things (the 93 octane one I think) is good for 225 to the crank. Thats the same as a WRX, with better gearing, lighter weight, and less drivetrain loss. Racing from a roll is easy too so..... I'm not callin BS, it just doesn't sound right.
