Has a little to do with a stock tune on the ihi in the lb7's. My other truck was a 2wd, reg cab and on the stock tune, the only time i could even get the 245's to spin without boosting was when the truck shifted to 2nd.
It takes a little while for the turbo to spool on the lb7's in stock form. Put a tune or programmer on the truck and you will notice it light up quicker. Spinning 33's and 20's is gonna mean some power though since they're probably gonna be a bit heavier then the stock 245/16 combo.
lb7's are not weak off the line at all. all you need is a good tune. mine will spin my 35's on command
