Im not asking what boost creep is i know what it is, i was just asking if anyone had run a screamer or a decat with roughy the same mods as me, the reason im asking is because i know the ct9s wastegates are small and i want to know if it will defo make me hit fuel cut? Because ive read alot of people on here say a decat will make it over boost and hit fuel cut. Im pretty new to the starlet scene so i thought id ask on here, but tbh im just gonna buy a decat fire it on and see what happens, i get no boost creep whatsoever with my filter and fmic so i doubt a decat will make me Hit fuel cut, ive asked a few local people with close to standard starlets with exhausts and decats and they dont hit fuel cut so i dont see why mines will but hey ho im just a newbie
