I'm running a Performer RPM with a one inch spacer at the moment. I'll most likely end up swapping intakes later this summer as a test just to see how she works with a single plane intake.
The engine runs like a beast with the Performer RPM but I don't have 8 02 sensors so I can't tell you if I'm having distribution problems or not. look at all eight spark plugs now before changing the intake, they will talk to you Isn't to much power almost just right

If the sniper is anything like the hp/ avenger/dominator, SUPPOSEDLY checking that box makes changes in the background that doesn’t require any changes to your maps. Hp/ dominator check box also allows throttle percentage changes to coincide with injector cut in/ cut out. I’ve personally used progresive linkage on a basically stock engine, worked real nice. I never switched from one version of linkage to another on the same engine to see if it does what it is designed to do though.

The sniper must really rely on the TPS like maybe it has some Alpha N mixed into its program. If it was speed density then it wouldn't matter much other than accell enrichment strategy maybe.

Checking the box with a dominator/ hp/ avenger ECU effectively switches the ecu to staged injection if wired correctly. The primary(front) injectors will be on at all times. The rears will ramp in at the tps position selected in the software. I found the factory setting on the avenger system to be pretty dang close to what it needed to be. I decreased the secondary value just a small amount to clean up a lean spot that you could see in logs, but not actually feel. I have not dealt with a sniper system. Does it use an hp ecu or is it something else?

Ok didn’t know anything about the sniper system. My suspicion would be that they use the same software, but there are probably not configurable injector drivers in the control unit. My advice to you is follow what Holley recommends.

Does this software have the capability to save multiple tunes stored in the ECU or is it one and done? Or can you import tunes from a laptop?
It would seem to me that the mapping between progressive and one to one would be completely different.

Thanks for the info Andy, I've never played with that system to know. Interesting as I assumed that you would get to similar rpm numbers with different throttle body area combined with a different TPS position thus requiring a different tune. Please keep us informed on what you discover and thanks a lot for the data share!
