TIA,

Sensor was actually brand new from Al and the team, and according to its self calibrating values at startup, it supposedly is accurate. I'm likely going to be replacing it after trying a new sensor if that doesn't help.
The tune that Al provides out the gate is perfectly fine for driving around when you first get started - speed density, pretty fat and rich in most areas for safety. But when you wanna dial the car in, Alpha-N is generally advised for ITBs and the whole tune had to be re-done. Al is upfront that he recommends a tuner to look over the car once you're up and running.
And yes, ill grab some dyno graphs - we're actually doing a follow up as I fixed a few things that weren't right with the car - cam timing, valve adjustments and a few other odds and ends
