I installed my Vararam today and started my tune. I have HPTuners and a AEM Wide Band. Did a couple of scans and looked like the MAF was off by about 3%. Scaled my MAF 3% and everything looks good now but my WB o2 sensor crapped out. The sensor has about 10,500 miles and is 2.5 years old. So I did not get to log any WOT runs with my Wide Band. My outside temp was showing 68° and logging intake air temp showed 73° cruising at 70mph.
