Well to paraphrase Harry Hill, what's better a PSI Box or a Remap?
There's only one way to find out...

Why not go for all the lot, plus a K&N and one of those magnets you fasten to your fuel pipe with tie wraps. With a bit of luck you could get 500 BHP and 75 MPG. In other words DON'T believe everything you read in makers bumf. Look carefully for the words COULD and CAN within them. You will not see "Gives an extra 30bhp and a 10% fuel saving". Because it ain't possible. If you use the 30bhp you WILL use more fuel. Simples.
