Can anyone tell me what's the best programmer tuner for a 2008 f150 harley davidson truck with the 5.4 factory superchargerd engine I'm having a hard time finding a compatible tuner, most tuners are for the engines that are not supercharged. thanks

 

I am fairly certain you will need to find a local, reputable tuner with a dyno in their shop to augment your current tune. As I understand it, off the shelf tunes are made for N/A motors.

 

What blower?

JDM for an email tune although there's lots of decent tuners out there.

But, A Few hours on a Dyno = Priceless
