Isaacxr6t New Member 20 Member For: 9y 7m 17d Posted 09/12/15 11:58 AM Share Posted 09/12/15 11:58 AM I own a 2004 ba xr6t with a standard turbo.I have noticed that when my turbo spools under load (generally in 4th or 5th gear) it makes a strange surging noise. The spool does not sound constant like it should. I have no idea what the problem may be. Looking for ideas?

They do can overboost if loaded up in high gears on the highway, depending on parts fitted and the tune.

So is this issue an indication of over boost?

It's tuned in open loop though which might make it more prone to stuff like that.#1 tip is PICK A GOOD TUNERYes, caps were necessary.

RaceEquipped Member 52 Member For: 9y 4m 2d Gender: Male Posted 13/12/15 01:54 AM Share Posted 13/12/15 01:54 AM Most likely a wastegate/boost issue (low rpms) the wastegate may be inconsistently opening/closing as you hit the threshold. Best bet is to go over vacuum lines to the wastegate, and install a gauge to see whats going on.
