Because Holley Thought You Might Be Interested...
Yes--Holley does offer an upgrade kit for owners of the original Sniper to move to the Sniper 2.
But before you get too excited, let's take a look at what's not included and qualify for whom this will be of benefit.
First, let's look at what's not included that you have to "bring over" from your exising kit or buy separately:
- Sniper Main Wiring Harness
- Sniper O2 Sensor
- Sniper Coolant Sensor
- Sniper I/O Harness
- Clamp-On O2 Sensor Bung (if needed)
- Coil Driver Module (if needed)
This in addition to the normal things that you might need to add to any Sniper EFI installation, such as fuel system, air cleaner, ignition, etc. In particular, note that the Sniper 2 does NOT have a built-in fuel pressure regulator option, but that the upgrade kit offers an optional external fuel pressure regulator for an additional cost.
...and how much am I saving?
Well, that depends on whether or not you're replacing a Sniper with built-in fuel pressure regulator and if you're in fact using that regulator currently. If you already have an external fuel pressure regulator on your vehicle then you'll save $200 (at the time of this writing.) If you are using the built-in regulator, that savings drops to $100.
That's not a big difference. Is this upgrade going to benefit me?
That's a decision you're going to have to make. But I might suggest that unless your existing installation is absolutely flawless and relatively new, and unless you fully expect to turn your existing Sniper into a paperweight, pay the fairly trivial difference and get the whole new Sniper 2 EFI System. That way you can uninstall your existing Sniper completely and proceed with brand new components. Moreover, you now have a complete original Sniper which could be either sold, gifted, or repurposed on another project.
Okay, so what are my options here?
Holley offers upgrade kits in either the polished or black version (sorry, no gold) and with or without an external fuel pressure regulator. Included in all Sniper 2 Upgrade Kits are the 3.5-inch Digital Display, since the display from your original Sniper is not plug-compatible with the Sniper 2 display.
Whether you buy a new Sniper 2 or or the Sniper 2 upgrade from EFISystemPro.Com included at no additional charge is our Level 3 Platinum EFI System Support. Our Tier-3 certified support technician will gladly talk you through any challenge--same price, but just try to get that sort of personalized service from a big-box auto performance store!
