I recently had a 2.85 pulley installed and tuned. The temperature was 45 degrees and I did a wot pull and my afr dropped to 9.5-9.6. It typically stays in the 10.5-11.1 range. I specifically asked for more power, but wanted a conservative tune. I know people typically tune theM at 11.5 The place I went was not specialize in Mopar, but works on a little of everything. Is this safe???
