Losing Power around 3-4 rpm after jb4 please help

Zechariaha · 12-29-2011, 09:35 PM

I installed my jb4 the other day and it ran solid for the first three days and then today i was driving and it starts to lose power around 3-4 rpm in every gear except first. It almost seems like it loses all power and then all the sudden it goes right back into the power band until go into next gear around same rpm's. Has anybody else experienced this or know what is wrong any help would be appreciated thanks. Car is all stock except for jb4 and it is in map 1. frustrated = (

Why would anyone here be able to help you? Email a CSV log in to BMS. Just a guess maybe you're triggering an internal safety system causing the JB4 to cut boost.

Just thought maybe someone had the same problem and knew what was going on, just a shot in the dark thanks for your advice I will have to do that. Thx again

When you find out why this is happening, please post too. Maybe this may happen to someone else and after a short search, they can resolve their problem quickly. After all, that's one of the reasons for forums and sharing info...

He means you posted in the wrong section. Nobody in the N55 section will be able to help. A slider might have came loose.
