[QUOTE=scap99;3743240]Read this book, please...
Not trying to start a fight, but my truck (5.0) would shift out with the stock tune. As soon as I tuned it that stopped. The reason I believe this happened is because in the stock tune the throttle plate would close between shifts enough to create a vacuum to pull the hubs out but once tuned this no longer occurred.
I do agree, using 4wd will lower your trap speed (MPH, by about 2mph in my case) but will also lower (improve) you ET in the 1/4 because you 60' is so much improved on a stock like tire.
I will also add that if you feel the need to argue this please use the search function first. If that doesn't suit your fancy then please, start a new thread about it, not let's not congest this one too much.
