Djov132 New Member 7 Member For: 2y 12d Posted 16/07/22 10:55 PM Share Posted 16/07/22 10:55 PM Car Is having boosting issues especially when cold new plugs new coils, when driving it seems that the revs get stuck and a popping noise can be heard from the turbo side but then hits boost straight after that. Car has a few mods bigger fuel pump, injectors, exhaust, external wastegate, side turbo intake, after market intercooler, and a screamer and is also on 12 psi of boost would love some advice to lead me to the right direction cheers Link to comment Share on other sites More sharing options...

I'd get it run up on a dyno to check air-fuel ratio's and the relevant tune run-up. Link to comment Share on other sites More sharing options...

Djov132 New Member 7 Member For: 2y 12d Posted 16/07/22 11:16 PM Author Share Posted 16/07/22 11:16 PM @k31th you can definitely hear the popping noise it happens 1 or 3 times while it’s hitting boost and with just hold the revs and won’t go anywhere then 5 seconds later it would boost hard. So you think it’s a tune issue? Link to comment Share on other sites More sharing options...

Easy to check and easy to fix. Link to comment Share on other sites More sharing options...
