Default The more I read the more confused I get - 04-29-2019, 10:05 AM

So Iím new to turbo cars but am solid with a timing light and a holly double pumper. Please forgive the lack of current tech speak.
I got problems(donít we all)

Looks like run I logged in map 4 is labeled map 1 and run starts at marker 550 on graph and runs to 710.

1) Added JB4, got the misfires and replaced plugs. No more misfires! Whoo Hoo!

2) Now Iím getting overboost code when in tune 1 and 5. Only tried 2 once with same result.

3) Went to drag race yesterday and logged some stuff but the data doesnít seem to line up with the graph. Best pass 13.91@ 101.74. Not proud of it.

4) Best I can tell when in map 1 or 5 the throttle drops in and out with pedal at WOT when JB4 is on and past approx 2/3 pedal position. Logs a code just a second or 2 into WOT and feels like boost is on/off/on/off instead of clean pull.

5) Car seems to run well and not log any codes with tuner off.

6) The attached files seem backwards from the map I was on. I was not able to run a pass w tuner on but did get a pass w map 4. I think itís lables as 1 if I see the data correctly.

7) The whole update software and do back end flash has left me very confused. Is there an update and back end flash set of instructions for dummies? G5 cutting diodes, which one to load and can I do back end flash through my mobile app or do I need the cable.

8) Itís the wifeís daily driver and she I asking me to pull the plug on all of this. I just wanna go fast. Please advise.
