Hi there,

Currently FBO (intake, Catless Downpipe, charge pipe, inter cooler, m performance exhaust on an OTS 93 octane tune from BM3). Ordering the 3.4 Big Boost kit and I know I need to upgrade fueling to get the most out of it. My question is what pumps should I go with? On the LPFP side, I was looking at a stage 3 pump from Spool along with a HPFP FX-180 pump. Will these 2 pumps be enough to deliver adequate fueling? I've had different answers from different people but want something definitive before I purchase. I've also been told to go the port injection or methanol route but am leaning towards upgrading both pumps. Any thoughts on this or what else I should grab beside the pumps and the BB 3.4 Kit? I know I'll need a custom tune.
