catback yields ~10-15 on stock map, probably 5 more on forthcomming, mature s1 maps. Anyone have numbers for the super sprint T-back and Procede?

my prototype catback was making about 18whp.
I'd assume that a 'good' tune would bring that up to 25 at least.

Maybe if I ever get a damn fuel pump, I can check that out for you..... ;-(
