Hi guys

Just a quick one see if anyone knows ....when i accelerate say from gear 2 - 3 there is a 2/3 delay for the boost to kick back in?

Anyone has any idea what it could be

Cheers
 
Hmmm I have a GFB DV + installed though surely the upgraded ones shouldn't do that?
 
I'd have thought it'd be alright to be fair! Tried putting the OE one back in see if it changes anything?
 
Was an error code on my ECU ... must have been where i swapped the diverter valve to the GFB+ one ...garage cleared it and is all good now
