i know the VK EFI manifold on a certain motor had a really odd high point at lower rpms, then dropped off to a normal ve curve, i can only assume it had some super good efficiency at that point in the inlet

if theres a big lump in the VE table then yeah probably is a bit odd....

The exhaust on the one /'s you tune, are they dual exhaust or single outlet, the one I tuned was single, was 4.9 a/f low end, 5.5 - 5.4 seemed to achieve max power top end.

it was twins, they changed it to single after the dyno though.

Do these wingless sprinters always run the VN/P computers, is it a requirement to do so, or can / do they run VR computers as well.?
