The monoblade defeats the IAC distribution compromising idle and fouling rear plugs. In no way worth the hassle unless you have at least a solid roller stroker and even then probably not worthwhile till reving past what the computer can handle

He told you to spend at least $100 more than you have to just for a TPIS top plate. If you are going 52mm no need to spent the $280 TPIS charges not to mention their $300 core fee.

If you want a fast car OR have a budget avaoid TPIS, mostly they cost a LOT and perform mediocre.
