Not sure if the gain would have been much had I installed the CAI before upgrading the exhaust & Pulsar but it was very noticeable doing so afterwards. Super pleased w/ the quality, appearance & performance! Thanks to Nick @ GotExhaust for the discount & same day shipping! Some may wonder why I didn't go the VaraRam route - I wanted to keep an airbox in place to obstruct the Pulsar from view for when I take the truck in to the dealership for oil changes. Not overly keen on having to remove the Pulsar, unless absolutely necessary. That was also the reason I passed on the S&B option... if/when I do need to remove the Pulsar for a service visit, I didn't want to deal w/ a PITA CAI removal process to get access to the PCM. Long story short, the Momentum GT Pro 5R was the best option for my needs & I could not be happier w/ the results. Pulls harder throughout the entire RPM range, SOTP gauge so take that for what it's worth but I am confident this was a worthy upgrade.
