I have a 97 f150 xlt 5.4l v8 with the 3.55 limited slip gears. what can i do to gain more low end power? Im building a prerunner out of it and could use some inexpensive low end torque. I already have long tube headers w/ true dual high flow cats and flowmaster super 40s and intake. im leaning away from chips and tuning
i agree with the tune and new gears. while you're in the diffs i'd upgrade the rear to a tru-trac or full selectable locker.

why are you afraid of the tuning????, an off orad tune would help you out a bit also

thank you for all the info, much appreciated! im not scared of tuning, just trying to find a reasonable price. is there anything cheaper than the gryphon/php tuning? i know its cheaper than the edge evo but maybe a little lower is what im looking for
VMP tuning is $400 with the xcal.
PHP is around $450 i think, but you get a screen.
dont go with an edge, superchips, diablo, etc. custom tuning is a completely different category of tuning and 100x's better.
a way to keep it cheaper buy a used xcal (can pick them up for around $150-$170, then spend the $50 on 1 tune so your only in $220ish bucks at that point, and the improvement will be incredible.
the tune will be written for any mods you have to help maximize all possible gains.
