Share. Tweet. #1. Sniper Tuning Help. 07-25-2024, 06:30 PM. First post on the forum, but would love someone's input. To start out, I have a Chevy 305 with a Sniper, Holley Dual Sync, MSD coil, T51R mod turbo setup, stock heads, comp cams 12-211-2 cam, mostly stock internals. The problem I'm having is, over time the engine has developed a small ...
Download the Config File currently in Sniper memory. Use Save As to give it a unique name so it's not confused with the Wizard tune file (s) on the SD card. Next, turn on the ignition and start a datalog. Start the engine and once it's idling, stop the datalog. Zip the datalog and the datalog files and post them here.
No doubt Holley could improve the Sniper experience without too much effort. They could fix the horrible timing curve that the Wizard builds, get rid of the Simple tables and default everything to 2D Tables and stuff like that. They could also hire an expert to help them harden the Sniper against RFI noise.

New Tune Advice. 05-11-2024, 06:51 PM. Hi all. Would really appreciate the experts advice here. Installed the Sniper a few months ago on a freshly rebuilt (but already run-in) 383 stroker, and it's been running perfectly. Let it Learn for about 500 km, then made a few adjustments to the timing & fuel tables, and was happy with the result Engine ...
First drive problems. 01-26-2024, 01:24 PM. Well it's not snowing or raining, so I got to go for a drive, and I didn't think I was going to make it back up the hill to the shop! I did one Transfer Learning To Base and then it stopped Learning all together. It idles well, but is VERY unhappy to drive.

Tweet. #1. Still High Fuel Pressure After Regulator Replacement. 09-18-2024, 04:51 PM. As the title implies, I recently replaced the Sniper internal fuel pressure regulator after noticing the gauge on my fuel inlet reading 65+ PSI, and performance taking a notable hit as well. After replacing the regulator (I know external is ultimately better ...
