first off i would like to apologize if this is a repost i know how annoying thy can be, but i searched abd could not find anything


2nd i have stock 9 with a tbe catless exhaust with a drop in k&n and whenever i floor it in 4th or 5th the boost will spike to 1.3 - 1.4 bar for a second and then go back down to 1.1. it will keep doing every few seconds as long as i have it floored


any ideas ?

many thanks mike

 

My testpipe did that for me. Get a tune and everything will be fine.

 

Do you have a stock o2 housing?

 

good to hear i was planing on getting it anyway once i save up.. thanks


yup
