Hi ,my tuner sent me a tune for my 2003 truck (LIGHTNING) and I'm making 700+ at the rear wheel. do you think I'll need a dyno tune ?? thanks
You posted in the wrong group, this is a gen1.

There should be a instruction, which should be in your email tune. Usually the first tune is a "safe" tune. You need to put in some more miles and send back the datalogging to your tuner to give you a proper revision. It may need a few revision before it is perfect.
