In my opinion an adaptation to the individual engine set up (air supply) is necessary. Without increased air flow (turbo, IC, exhaust) the potential of larger elements can not be used. Further to this I recognised a different curve shape of fuel flow over rpm which has to be respected in comparison with the curve of air flow over rpm to avoid black smoke in the whole range of rpm.
I.e. with my 6 mm (HOLLY-) MW-elements I must live with dead bottom power (stock turbo not sufficient air at low rpm) to avoid black smoke.
This will definitely change when the VTN turbo, IC and exhaust mods are done.

Where did you have these elements made?

I have the other mods needed already, now I need more FUEL!
