Hey guys! Just ordered a gauge pod for my gmc sierra. It's a 2011 5.3 with a magnacharger, jba headers, 6.2 exhaust and dyno tune. I ordered a wideband to keep an eye on my a/f ratio off the dyno. However, im a lil curious as to the best place to put it since there not much room between the collector and cat. Would it be better to put it after the driver's side collector or in the the #7 primary tube? I've read that the #7 cylinder runs the leanest on ls motors.
