Couldn't agree more mate, my Blitz has transformed my car, is holding around 18-19PSI in top channel.

I made 285.2BHP and 333.5lb/ft yesterday with this...

Ford Motorsport Manifold
Mongoose Decat
Mongoose Exhaust
K&N Gen II
Pro Alloy Charge Cooler
Bluefin
Blitz SBC ID 3
Bailey DV-30
Samco Boost Hoses
Denso Iridium ITV-22's
Magnecor KV80's

The way the boost comes in now in top channel is so aggresive they had big probs with traction on the rollers!
EAs figures do usually seem a bit optimistic tho imo.
