I remember there being a topic on this forum before "the big clean out" on tune alterations to hego parameters for long tube headers so that it would compensate in the different exhaust pulse that long tube headers present.
I was curious if there were parameters that need to be changed, and if so what they were.

How far does the delay need to be adjusted for a set of longtubes?

Re: Longtube header tune alterations
