I reciently put MLS headgaskets on my 89sc. While it was apart I had the heads redone and ported. Had the whole induction system gasket matched. Added a 10% pulley. Ported the manifolds and added an ic fan. The car is no faster than before and has no more boost (Still idles at 18in vac and has no mre than 9-10 of boost) .Shouldnt I be able to notice a difference? It idles like it always has with the occasional barley noticable roughness. Everything was done right. And the ic tubes are sealed well.Any Ideas? Thanks Derek
