with any log manifold above 7k ideally.
log manifolds are restrictive and during vtec the valves are opening with more lift and duration causing exhaust gas reversion and detonation. you raise vtec so you can somewhat limit exhaust reversion.
this is what tony told me at T1 when i got tuned there.
I sold my greddy kit like 2 months after i tuned it because it sounded like it was causing detonation above 8k rpms. sounds like rice on tin foil

would it be ok to drive about 20 miles to my tuner on a base map? he came and loaded the basemap and made sure everything was ok. mechanically i know it will be ok. like oil lines and what not. ive only driven up and down my street with it on. im sure it will beok to drive it there. just dont hit boost and take it easy right?
any experiences or thoughts?

thats another thing...i have an auto meter a/f gauge. i havent hooked it up yet. this may sound dumb...but A: how to i hook it up? and B: is there a way to tap it into any of the emanage wires?

The greddy manifold is very restrictive and the small turbo doesnt breath enough for the F2xc. When the exhaust valves open under vtec especially spent exhaust from the manifold is pushed back into the cylinder and it has zero oxigen in it. The heat from these gases can cause the new air/fuel mixture to detonate. The pressure in the exhaust manifold is roughly twice that of the intake manifold.
You dont need a fuel rail until you wanna make 600+hp, Use wiki for the blow of valve q's

The Pfab manifold has like 3 times the internal area that the greddy manifold has.
If you get it tuned well you don't have to worry about detonation. I had no problems with my kit detonating. I often drove and checked my logs after, or drove and had my wife holding the computer and watching the vitals. I had a list of 10 different things I looked at. Just run 93 or above, get the correct plugs and gap them correctly, get a good tune and be happy.
