Any real data
Ok I'm looking to install one of the tuners advertised out there. What I would like to know does any of the guys/gals that have downloaded a hand held...Predator...... do you have any clear evidence other than feel that it improved your performance.
I'm wanting to install one.I have 385 rwhp from a Hennessy CAI and QTP cutouts. Will I get hp/torque Gain with just those 2 mods.
So if anyone has limited mods and a handheld tuner with data please reply.I don't want to waste money again!
