My SHM MAFterburner has allowed my Contour with larger than stock injectors to run a -1.5 to .5 LT fuel trim.

At WOT it jumps up to 38% ST fuel trim lean. But the 02 takes over at WOT. So the ST is off no value. The 02 values now read either .93 or .94 and .92 at the secondary actuation.

An useful tool.
