Been running stage 2 for 70k without an intake as I hated the noise and the car pulls and drives just fine but that's an ed30
Agree with Matt.. I never ran an intake on my ED30 until it went Stage 2+. I ran it with Stage 2 (Milly TBE and panel filter) for 18 months and it was plenty quick enough..
Only went for an intake in the end when going Stage 2+ .
One of the most noticeable things about going Stage 2 is the DP and spool up. Huge difference IMO..
