Member 69 Member For: 17y 4m 19d Gender: Male Location: Mildura Posted 13/03/09 11:07 AM Share Posted 13/03/09 11:07 AM Hey GuysI have the usal mods, PW stage 1 cooler, Crow Valve Springs, UBP, Walbro, K&N, wastegate mod, stock high flow cat and a 12 psi actuator.Basically what my problem is the most boost we have been able to get out of it was 12psi. And that's running ALOT of duty to get it there. Something is choking it somewhere along the way but I haven't been able to pin point it... My current tune is a 10psi tune that holds 10 psi all the way. Now I was on the understanding that with a 12 psi actuator I wouldn't be able to run under 12 psi?Has anyone else had this problem? or maybe someone has some insight into what could be the problem?CheersBB Link to comment Share on other sites More sharing options...

Where is your boost gauge signal taken from? Edited 13/03/09 11:43 AM by PHANTMXR6 Link to comment Share on other sites More sharing options...

Before that goes any further, dataloging also says 10 psi. Link to comment Share on other sites More sharing options...
