View Full Version : boost hopping????

08-14-2007, 02:13 PM
So i finally got my boost gauge installed, and i made sure i checked all the hoses and everything... when im in 2-4th gear, and im in like anywhere from 2000-4000 rpm, if i give it full throttle, the boost is jumping and i can feel it too... it goes from 8-13 sparatically and then finally levels out to 8... anyone know what this can be?

it goes to 13, then back down? or bounces around b/w the two for a second?

sounds like its bouncing between the two not just spiking once then holding

its bouncing between the two for a couple seconds, and you can feel the car and hear my exhaust when it does it... it just doesnt feel normal... it goes up to 13, down to 8, up and down up and down, and then levels... its like instead of spiking, it bounces

Did you install a different N75? Could be your diverter valve. Whats your mods list?

whats your vacuum at idle and does it hop then?

ok my vacuum is at 20 at idle, and it doesnt hop.... my mods list are exhaust intake and boost gauge as far as performance mods go

you have the stock DV in? If so buy a 710n or find someone with a aftermarket DV and swap it in and see if it still hops around.
