Minimizing Boost Taper at high RPM: Pill or WGA ?
Dyno day @ HB Speed is just around the corner, I want to minimize the amount of boost taper at high PRM.
What is the best method to accomplish this?
Boost Pill or WGA?
Maybe HB Speed can chime in on this one, also?
Thanks!

ps. yes I searched. and this is a 2010 GSR

Ummm...you can hold quite a lot of boost inter upper RPMs already if you tune right and tighten the WGA. HB Speed will know about it. And since you're going to them to get tuned, he'll also know to check the IDC to make sure you aren't running your injectors maxed out. I've notice that on some people's MRs, holding 22-24 PSI up high with some other tweaks, its not difficult to hit IDC of 95+ %...what I would consider too high for comfort.

Im also wondering his reasoning behind this... I have upgraded to the GM 3-port, and is one of the best mods yet! You spool a lil bit quicker, and can hold more boost everywhere in the range w/ minimal duty cycle...
Maybe he only tunes w/ MBC's?
Like has been stated, you do not need an upgraded WG on the stock turbo! A couple turns on the stock 1 to tighten it up, and should be good to go. I just had my turbo ported this weekend, and had the WG tightend, and its now holding 1 psi more @ 7000(22psi w/ ~ 84%) porting helps, but I think the WG is doing most of the work. Any more than that is just taking the turbo out of its efficiency range.
