Red top, Big & small port computer swap.

[Jebus]

Was reading on Bill Sherwoods 4AGE write up that by running a bigport TVIS red top on a small port Red top ECU, you can get better top end at the sacrifice of low end because the TVIS stays open. Wouldnt this just be the same as running without the TVIS plate?

eg, fitting a small port computer to a TVIS big port engine and making the TVIS stay open will often make the engine go better at higher revs, but worse at low revs)
