Did you remember to do a throttle adapt after you changed the N75??

and if it is the "race" n75 from ECS it has been reportted to not be the best with chipped cars.

Agreed, stick with the stock n75, it is what the tuners have installed when they make their programs

RIf the car dosent run right with the "race" N75 then...

Why use it? Perhaps Revo dosent allow it, dont waste you time, its just going to make the car slower and hit fuel cut, if that is the actually problem.

"Race N75" is a load of crap.

Just cuz Tom'll sell you one all day (at twice retail) don't mean it's going to be good for your car.

Race n75 : If you are running 1 bar this wiill cause spikes =limp mode(fuel cut)......

I am running Oct stage 4 and I was getting spikes up to 25lbs. Tried everything You can possibly think of.Pressure test for boost leaks,diverter valves and alot more only to find that my previous tuner placed this darn race n75 in my car, which I suspected was the cause of my ko3s meltdown with the x chip.So anyway after stock n75, Iwas getting less boost than requested so I tweeked stock valve buy turning screw on top untill the requested boost was achieved.Been running steady 21Lbs scince.
