understandable. The S1's have an idle as well. I'm sure they are not as bad though. Talk to your tuner. see if they can tune the idle to make it reasonable.

 

my s2's idle almost like stock, no lope, slightly meaner idle tone..

 

from what i was told by my tuner is the FP red is a beast on 91 oct. I dont have any other fuel sources around me. so its 91 for the win. I was on the fence about the bbk and the fp red. all he had to tell me is the red leave lots of room to grow if you want to the bbk will max out somewhere before. im shooting for 450-500 range. i wanted the bbk and he promptly talked me out of it due to the fact if you ever want to get just alittle more power the red is the way to go. Get whatever turbo you want for your setup i say who cares what your tuner says lol because he is gonna tune what you put in front of him anyways. just promptly let you know what you could have had thanks MELLON

 

yep...

you have to pick what is right for you...
