im running the br7ef's in mine, two steps colder and non-projected. Running full timing on the 100 shot and i have a IAT timing tricker wired up to pull 4 degrees of timing when i run the 150 shot. I cut a 1.64 60' spraying outta the hole with a 3600 stall and bone stock 5.3. And that push button switch is a bad idea my friend, ive seen a couple nitrous backfires because of it. Play it safe for now, but i would save up for a harris speed works microedge.
