It's basically physical dimensions of the HPFP piston and chamber, you can measure the piston if you open it up. Or just a "ballpark" percentage change of the piston area and then volume re-calculation will do, if you don't want to open it. Adjust later if control looks wonky. |

I guess vis motorsports is 10mm is piston size inside how would you do the conversion to edit the map?

Just calculate it, like everyone does |

is this the right way for the calculation
RQUAHDPK = ( 10 / 2 ) ^ 2 what dose the ^ mean when doing the calculation i tried but i didn't get close to what it should be
for VHDP it would be what RQUAHDPK = then x 3.14 x 5?

^ means for example 2 ^ 2 = 4 X ^ n = multiply X with X self for n time ... 4 ^ 5 = 4*4*4*4*4 In your example ( 10 / 2 ) ^ 2 = 5 ^ 2 = 5 * 5 = 25 |

The for VHDP would be 25x3.14x5= 392.5 dose that sound correct
Would SKHDPMX stay stock since it uses stock spring?

Unless you fit a CDL cam, leave it stock |

no i didn't change the cam i left it as a BPY cam
When using a uprated HPFP its a must to Change map RQUAHDPK and VHDP is that correct?
im waiting on my RS4 to show up to up my fuel from 130 bars to maybe 140 bar.

Indeed what i said... if it is CDL engine...the formula is different |
