chaydon1 Member 42 Member For: 11y 9m 6d Gender: Male Posted 28/08/13 11:10 AM Share Posted 28/08/13 11:10 AM (edited) that's not really answering my question but anyways. Ive had no tune with a full exhaust system put on. no engine lights and an electronic boost controller. And everything is tip top. had it on the dyno everything is great. Touch wood.The boost controller is stopping any overboost and no engine lights are on from cat change or exhaust change.and running better than ever. sorry for hijacking the thread guys just sharing my opinion.EDIT: I have a tune for all my prevous mods obviously just no recent one for exhaust.

Brooksy-BFXR6T Member 14 Member For: 12y 6m 4d Posted 28/08/13 11:41 AM Author Share Posted 28/08/13 11:41 AM It has obviously been tuned previously (8psi tune, 10psi tune) and I've only boosted it once since putting the exhaust on (might hit 1-3 psi every now and then) and I watched the boost gauge, only got to around 10psi? I was expecting an a spike, but nope?It will be getting tuned, just wanted to see if throwing the sensor back in would help at all. Link to comment Share on other sites More sharing options...
