370z Supercharger Boost Issues

My car is not with me atm but hopefully I get it back from the shop soon. They saw my email about the car running lean and knocking and called me to bring the car in last Wednesday. Haven’t heard back from them yet but hopefully they are making good progress.

Will keep you guys updated

THE BULL

One of the things I would check are your MAF jumper harnesses since the signal is a shielded wire and the jumper is not. It's possible you might be having MAFs sending an incorrect signal

However being that it's a reputable shop and BYthabay has tune many of them stick with them. Hope you get this resolved.

The shop ordered a brand new Stillen extension harness for me as it was missing in the kit but ill have a look at it.

Got the Topgunz anti slip pulley in but it still made the exact same boost. So it's probably not the belt or pulley that's causing the boost issue?

Not too much of a mechanic head myself but I do still want to get this all sorted...

Anyway, regarding the tune, we're having an issue now where the maps will randomly disappear. The first time it happened, I brought it back to the shop and they flashed the maps on it again. I drove it home the same day and it disappeared again on the second start up.
The shop suspects it's the ecutek bluetooth dongle so they took it back to their shop to analyse it. They flashed the maps back on again yesterday and it hasn't disappeared yet.

Take the intake tube off and run it filterless for a pull. Process of elimination by taking away potential variables.

I’ll get the tune sorted out first then will check if the intake is the issue. Still a couple of things that needs fixing with this set up unfortunately
