Sorry if this is the wrong place for this. Wondering exactly what Westers is. Heard there are plug wires out there advertising 15hp. Saw some MSD coils and wondering how much they are/hp gains. Is an aftermarket MAF sensor worth the $300. I'm thinking about getting back into a poor mans Corvette (Reg cab SWB 5.3). The one I had ran 9.8 1/8 mile w/ a hypertech, true dual straight pipe, 160 thermo, Volant cold air, TB spacer. I'll do some of this again but want suggestions.
