The manual isn't very clear on this. I have installed 87 tune, reset my tps, with no issues and fantastic results. But whats up with the crawl tune? Does installing this replace the 87 tune or supplement it? I have always thought the throttle was a might bit sensitive in 4L but reflashing everytime I drop into 4L would be a real PITA.

 

Anyone????

 

crawl tune seems to spread out the throttle. The problem is, the jeep already has a million miles of travel in the pedal to get to WOT so the crawl tune from what I hear is almost unusable. Its designed for very slow, controlled starts and eliminate lurching.
