PC is a must have (imo)... it makes the truck behave like it should have from the factory.
I posted similarly in another thread > I recently got out of F-150 2.7 EcoBoost with 3.73 axle ratio - it was super snappy and a lot of fun... when I got the Rebel I was a bit disappointed with the lack of throttle response...
I hadn't read any forums prior to the above... my cousin is a big Ram fan and I expressed my concerns to him - he said it was a common complaint and told me about the Pedal Commander... I did some brief internet research and was pretty convinced the thing would do what I needed so I ordered (nice surprise that it was 50 off with XMAS50 code)...
I installed it Christmas day and it absolutley brought the truck where it should be. Power is not a problem with this truck, lack of throttle response is - with the PC that problem is gone! Now my Rebel is every bit as capable as the EcoBoost.
It is not hype and it's not placebo - the thing plain works and as far as I'm concerned is a must have. A buddy of mine ordered one for his Warlock around the same time as me - same impressions.
PC by far is worth the small price. I have to believe it's the best bang for buck mod for this truck.
If you're on the fense, fear not - I'm positive you won't be disappointed. As to comparisons to Pulsar - I had read about that unit when researching PC... while I'm not dissuading anyone, I don't really feel the need for one (at this time).
