Mass air, Must I???

[Brian88]

i ran the b cam and cobra roller rockers with speed density. i had it tuned preety good, but i could not run any more injector than a 19. it was also preety hard to keep running in traffic and idle and cold. i switched to mass air and couldn't be happier. the cam became more crisp and i feel it pulls harder.

just my experience.

those 30s will probably be way too much for speed density to handle.
