I’m not sure if this would be the place to look, but I’m looking to borrow or rent a wideband or buy for cheap, I only need it to tweak my tune a little.
Your tuner doesn’t have one to use while “tweaking” your tune?
i’d assume by this post he’s doing the tune himself
yeah doing it myself working on idling and P/N/R/D switching issues
Isn’t synapse tuning your truck
not anymore ive had it for a while, im waiting for Howard to come in april to tune it further, but I want to try to address this high rev in shifts between p/n/d/r before I make a trip to VA, also some surging and throttle lag
