[s-cars] Chip upgrades

[Michael Lardizabal]

Taka-

Having owned a few V70R's.........they're all Mitsu turbo's.

The LPT models used 14 or 15g's , the T5's got either 16 or 18T's depending on if its a P1 or P2 car...and the venerable v70R's got 19T's. All configs are internal wastegate style turbo's.
