I plumbed and ran this hidden kit for several years on a oem small block six pack, still old school pig tips, I kept the same 34/36 tips and toned it down equally with big restrictors right at the inlet.

Never an issue, then went to the mini controller.

Only issue ive ever had was a micro switch stick...bad.

I wouldnt use a under the intake kit on a street car, seen many leaks, gummed up lines, and then worse, and I think are getting to be more left in the past...
