SS with Lt4 blower issue after sitting for 5 weeks

ss2fast4u · 11-06-2020, 06:57 AM

About 1000 miles ago I installed an lt4 blower with lt4 fuel system and jms voltage regulator. Janetty racing did the tune and it was running great. I parked it in the garage about 5 weeks ago and took it out last night.

It started right up no problem , idles fine and when not in boost drives completely normal. Once it gets into boost it starts to skip or miss and I can feel the vibration in the floor and exhaust. It’s really strange. I looked under the hood and nothing looks any different everything looks connected.

Could it be a plug or wire if it starts fine and drive normal under no boost? I also went and out fresh gas in case it was that but didn’t help.

Any ideas?

I'd data log the problem and send it to Ted for analysis. WOT is a different "mode" altogether, and the log will help pinpoint potential sources.
