For those who have had a timing box (Edge EZ, Van Aaken, etc )
and then switched to a fueling box (Comp , Blue Chip , etc.) was
there a huge difference or just a mild increase ?

 

The comp is a combo fueling/timing box.

 

There is a huge difference in the comp with the wire tapped and an EZ.

 

Oh heck yea there is. I remember when I tapped the wire on my truck and ran it on 5x5 for the first time. I was in love. It was amazing to see the boost go from 30 psi with the comp in EZ mode (mo wire tap) to 45psi and to watch the EGT's go from 1100* to 1500*+. Not to mention the smoke. There's a BIG difference.

 

Your basically doubling the HP from your present VA box....just remember what it felt like the first time you drove it. Should be the same increase all over again +/-. Biggest plus is in the mid range and the top end....where your present box does little.

Yup, the Comp is a fueling AND timing box.....and there really is no comparison between a Comp and an EZ.....The Comp makes your truck fly and pull like a freight train, the EZ does not.

As RJ mentioned, you truely are doubling your hp AND torque gains with the Comp over the EZ.
