Problem with Solstices

[igorsm]

Hi everyone.

I've got a problem.

I've recently tuned 2 Solstice GXPs. One on manual, one auto.

Everything is fine, but both have the same problem.

Sometime, when you hit the throttle they make no boost. Then you hit it again and boost is OK. Sometime car falls in reduced power mode.

They both have HKS SSQV bovs, cat delete and Apexi AVC-R boost controllers.

Boost is 1.6bar (22psi)

Under 1.1bar(16psi) everything is fine.

Any help is greatly appreciated!

Thanks!

Sounds like as prob with having a boost controller.

Disable overboost/underboost codes. Happened to mine and that fixed it.

As an alternate, you can change the enable rpm to something like 8200 rpm & set the diff to 255 kPa if you don't want to disable the codes.
