Stevieturbo Posted February 12, 2019 Report Share Posted February 12, 2019 With a bad tuner, they can be destroyed at less than standard power. With a good tuner they can easily support more than a VF37 will make. Quote Link to comment Share on other sites More sharing options...
Fotis Posted February 13, 2019 Author Report Share Posted February 13, 2019 Bad tuner with the meaning of what? So lets say maximum 450hp at the engine? Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted February 14, 2019 Report Share Posted February 14, 2019 Quite simple, bad tuning can destroy even the best engine in a matter of seconds. Fotis 1 Quote Link to comment Share on other sites More sharing options...

Fotis Posted February 15, 2019 Author Report Share Posted February 15, 2019 So how much hp is the vf37 maxing out? I have read somewhere 400-430hp (engine) Quote Link to comment Share on other sites More sharing options...
