I was on Lightning Motorsports website looking at the TurboXS boost controllers and there is a standard boost controller and a high performance one. On the high performance one it states that it's a ball spring design and gets you to full boost sooner than stock. I thought the only difference between the two was the ability to go higher in boost on the high performance one, but under the description for the standard one it doesn't say it's a ball/spring design or that it gets to full boost quicker. Is it the same design with just a more powerful spring and housing for the high performance one or is it a different setup that is better that I should get even though I only want to increase the boost to 7psi, 12psi If the motor goes and I rebuild. Confusing? Thanks
