Some of you will remember after i bypassed my n249 that i was worried because the "tsssssh" on my 007p changed to a slight but only very slight flutter. However i lost no power at all and my boost got to about 6-7psi then would fall and hold at 5.
Some suggested i try a yellow spring and thanks to dean giving me his i took the car out for a run and she still has that tiny flutter but now shes boosting well upto 10 psi and holding at around 7 now i know the general rule is green spring for unmapped and yellow for mapped but my question is would leaving the yellow spring in, would it cause any problems with my car not being mapped?
