sprinter Member 19 Member For: 13y 4m 24d Posted 25/07/12 09:36 AM Share Posted 25/07/12 09:36 AM (edited) ok so got my ba xr6 t back after having it retuned by kpm to fix a boost problem, it made 288 at the wheels but now its having a problem with what they said either spark break down or maybe valve springs!what does everyone think? could it be that the plugs need to be gapped/replaced "were replaced 15,000 ago" or maybe the coils? or valves?car has a bigger front mount and new pipe workbigger injectorand a growler induction kitbigger waste gate actuatorand a tune running 13 psi Edited 25/07/12 09:37 AM by sprinter Link to comment Share on other sites More sharing options...

Bf's, and Typhoons to Fg's can get away with a lot more power on std springs Link to comment Share on other sites More sharing options...
sprinter Member 19 Member For: 13y 4m 24d Posted 25/07/12 09:50 AM Author Share Posted 25/07/12 09:50 AM I might just bye new plugs anyway with less gap its not to expensive to do and see how that goes! other wise ill do the springs, any suggestions as to what springs to use?

Id just leave it with KPM, they will have experience in replacing valve springs. Link to comment Share on other sites More sharing options...
