Hi guys,

Ok so I have some mods coming up. Definitely going to get siemens injectors, typhoon air intake and k&n filter plus an edit....

Now thing is what do you think the power will be with the above combo ???

How much do you think I would get if I added a high flow CAT ???

Would you guys do the cat too or don't yoiu think it is worth it???

It's a 4 speed auto BA....

well for comparison.. I went to nizpro with a custom tune & siemens injectors and got 267rwkw.. with it topping out badly starting from just under 4000rpm (I.e. wont flow any more gas!)

my friend from work went in 3 weeks later and got the same thing, siemens injectors & custom tune.. with a 3.5" cat & made 302rwkw with heaps more midrange.

Mine made higher torque but I was making 13psi where his made 12.

both BF T's, 6 spd manuals.

If its an MK1 than u should be also looking into some Valve Springs... that's whats holding me back and I only have 227rwkw after a custom tune....

Cheers Mike..

Mate, the cat should be the first mod on your list.

:blink:

The standard CAT is a massive restriction as other posts have said. If I was you I would def be getting that done

cat is a great first mod (and dump if you can) - followed 3 mins later by a custom tune....
