boost gauge shot up to 1.6 on half throttle as it seemed to set it free from the restictions ..... kinda scarey and thank god I had a boost gauge with warning light and Zak and I checked. Without that I would have gone home loving the extra whoosh until the whoosh turned into a whirr click ckick bang

 

not au fait with the newer cars, is yours twin scoll or is that just the MY05 JDM sti's...I'd imagine that makes a difference to the amount of boost thats freed up from a decat?

i've not been to mocom yet, but i need to have my geometry checked so am going to book in soon...i've only read good things about them so am looking forward to the experience

 

i think im just gonna get a cat back system instead!!!!! im not really interested in gettin more bhp, just want to hear the burble and save £400 because im tight!!!
