None with the sniper system but even the factory systems need 50 start/run/stop cycles to "finish" the learning curve.  Seams time is not the issue but rather cycles.

I have a Sniper Stealth 4150 and a Terminator X computer. It uses the same handheld screen. I don't know about the Sniper 2 but it supposed to be improved over the Sniper. I have a laptop so I have started to learn about these systems (no expert for sure). I know the only learning the system does is to correct the A/F ratio. You enter an idle, cruise, and full throttle AF and the system adjusts the time the injectors stay open and develops an A/F map. It remembers the corrections but it doesn't apply them until you command it. I found that my car drove well with the start-up program by the Wizard function. I found there were some very large correction factors uncovering a developing fuel delivery issue (filter started clogging up). My system also includes timing control as well. The system can be tuned completely but it is not necessary unless you are having specific problems. What engine is your Sniper 2 on?

I have the Holley Terminator X Stealth and to tell you the truth , I think I would rather have my Quick Fuel 750ss AR back on. When I had my FE 406 Rebuilt I put the QF on her and had my engine builder tune it on his engine dyno. He was able to get 430 horse and 460 torque. Out of the box The carb is a kinda rich. Carb ain't bad sept the fuel mileage was like 9.5. lota guys tell me to go with EFI so I got the Holley Terminator X Stealth thinking I would get better mileage. I had it installed and set up on a chassis dyno  the stealth model opens all the blades together not in progression like most caarbs and optional linkage kit does not work on the stealth it seems like its, no go to blat off, not good with a clutch on a hill.and my Gas Mileage didn't improve.  Now I thinking all I need is to break down on the road because of the EFI at least a carb will get me home.
So in my humble opinion our old engines and and trans . don't seem to benefit from anything high tech today.
