Ok i recently had a new headgasket, ARP head studs,and a hondata intake manifold gasket installed. Sence ive gotten the car back ive noticed the car feels considerbly less ballsy in lower gears, and for some reason its not spooling as fast as before and its not reaching full boost. I know that the slow spool +lack of full boost is sympton of a leak, but after testing, no leaks were discovered. Now I did not replace the exhaust manifold gasket at this time, and it is fairly old, could this be causing my boost problems? I dont hear any exhuast leaks by the manifold though. Could this loss of power in lower gears be the result of a timing issue?
Any help or suggestions towards figuring this out would be apreciated, thank you
