As the title says which one would spool quicker? Some say the GTRS, some say the traditional 3 inch so which one is it and at what rpm would full boost come on?

I'm not sure about the GT RS but I have a GT2871R .64 and it reaches full boost at about 4k rpm. I had a HKS GT2530 that reached full boost at about 3400 rpm. I'll assume the GT RS will hit full boost about 100-200 rpm before the GT2871R .64, but that's just a guess.

I'm looking for something that hits full boost at 3.5. According to codyace the 3in would spool quicker but I've heard otherwise on FA. I will be extrude honing my manifold and swaining it. So would that bring it down to what I'm looking for? I'm only looking for around 350hp with cams so I guess fool boost for me would be 16-18 psi? How much boost are you running?
