Put on a brand spanking new APC onto the aero today and it has become the same 300bhp Fire Breathing Monster ( ) it was before I noticed a few problems. It's boosting much quicker now and pick up is much better.

I have noticed however and this did happen before I changed the APC but when I back off the turbo the boost guage drops down to something like -0.8bar. It's quick to rise again but I'm not sure if it should drop so low . Does this sound normal. (With the air-con off I'm hitting 1.2-1.3 bar)
