: Velocity ap tuning

[Gasman2]

Tbh not that worried about numbers
More how it feels
Never liked rolling roads and stuart seems to think they have the map preety spot on and a live map may poss net a 2% difference
My last car was a c63 monster 720 and 600 torque and was rolling roaded but that had more mods than brighton on a bank holiday lol

Be interested to hear your car with the velocity valved rear as well

[Timbo]

Oh its loud lol but i think one of the valves might be a bit loose, theres a slight rattle from the left hand side of the box!!

Upper pulley dont want to stress engine as crank is quite a jump in boost and needs plugs and for everythibg to be 100% at this kevel uprated intercooler not rqrd

From my reading on the Yank forums, the bottom pulley is the one to change along with 200 cell cats - VAP don't seem to say you need to do anything with larger intercooler or plugs.

[Gasman2]

The bottom pulley requires injectors and coil pacls to be 100% and though not stipulated commense sense dictates uprated intercooler and one heat range lower plugs...if i had awd i wld look at crank pulley

How do you find it post conversion Gasman?

[Gasman2]

Transformed
Much faster pickup
Pops and crackles even at low revs *they can delete thes is rqrd*
Sound evil
Tbh didnt really need it just wanted it and for the road again bot really needed but why not
