14cm W/G pros & cons

[ofelas]

Morning all

Would a 14cm wastegated outlet still flow decently allow me to still cruise at 70mph with 3:54/auto/33" tires without affecting my current mileage ?

For max mileage on the highway I want as little boost as possible while cruising empty correct?

This truck is always unloaded, no towing/hauling.

transmission has been rebuilt with HD parts, synthetic ATF, Transgo & a decent converter.

I understand a smaller than 21 cm housing gives me more usable torque around town.

Just a timing bump, turned stock pin and a less restrictive factory airbox; I don't plan on adding more fuel...famous last words :-laf

You won't believe the difference. The 21cm is a dog. My 18 cm was a dog but i live at high altitude.
