Reply to "Holley Sniper EFI install"

Just wanted to add my 2 cents here.  When I had my Sniper 2 installed, the throttle bracket was not moving all the way back, and thus I was not getting full throttle.  I don't recall exactly what it was hitting, but it was hitting something and the lever arm had to be extended.  I had a metal shop do that for me.  But when I took it to be dyno tuned, the guys at Race Krafters (Lancaster, PA...GREAT guys by the way) saw fuel was at 60% max delivery and hp was no where near what they thought it should be.  HP was coming in at around 290 (if memory serves me correctly), which they felt was way low for my engine.  Anyway, they took off the throttle arm, cut off the pin and moved it to the top of the lever arm, and adjusted the cable, resulting in 100% fuel delivery (according to their very impressive diagnostic machines).  After roughly 14 dyno pulls and full engine and Sniper 2 tuning, engine was producing 386 hp , with 405 ft-lbs of torque.  These numbers where at the wheel, so probably 445-465 hp at the engine. It is imperative to get that throttle body perfect or you are leaving a lot on the table.  Based on my own experience, I would say eyeballing the throttle body movement after the Sniper installation is not enough and it really needs to be tested and tuned on a dyno with folks who are experienced.  In my case, Race Krafters were/are Holley Sniper EFI dealers and installers.  I had called Holley and they looked up their dealer/installer networks and referred me to them.  I think no matter where you live, they will be able to guide you to someone who can install, test, and dyno tune the system for you.  GOOD LUCK!
