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
 
what other mods do you have done to your car? Since you have ported the heads boost may have dropped since there is better flow, but the 10% pulley should have brought that up. Also make sure you dont have a boost leak somewhere, was the collar nut on the sc top tightened all the way?
