Any 100-200? Should be in the 7s if its 447

[@RegalAutosport]

Haven't tested, but we would love to!

[@B58m140]

Dose bmw map the gearbox or is this a tuner thing

[@RegalAutosport]

We map the gearbox

[@appletango2424]

447bhp is crazy for stage 1 :o

[@RegalAutosport]

Yup! Pop a HPFP on there and we can see even stronger mid-range and top-end power and torque.

@@RegalAutosport Would it need remapped again with the fuel pump or if you have a Stage 1 car could you just add a fuel pump?

[@alexandercooper8743]

@@davidbolton8573 Yes you would need another remap to take full advantage of the Tu Fuel Pump

[@jasbhangra9735]

Was this an opf car???

[@RegalAutosport]

I don't believe this was

[@07908567]

This 140 produced 377bhp stock, that’s serious

[@RegalAutosport]

Proper!
