I did this mod some time ago when I had a LMR intake, I still have it with my CAI intake and washer bottle delete. Never had a CEL come on. Don't know if it's really helping for HP, but I don't think it's hurting any.
The day I take a bend too fast
Judgement that could be my last
I'll be wiped right off the slate
Don't wait up 'cause I'll be late, I'll be late
