2003 spec c tuning advice
 

Hey guys

Having just got my spec c it feels a bit lacking in power, is tuned just for uk fuel. Rolling roaded at 312bhp, currently in standard form,


I'm wondering what to expect really from a remap, I'm thinking decat down pipe, but will I need a new fuel pump, I may chuck a air filter in there too


Cheers guys

My Decat and fuel pump netted me about 10bhp over the PPP sports cat, so expect 325bhp if your car responds the same.

Will it not differ with it being a twin scroll

Decent panel filter, full decat 3" straight through and a map on a vf36 should see 370ish give or take with similar torque. Twinscroll make decent standard figures when mapped nicely.

If you want a bit of thump think of a LM series or a sc range. I've got the lm450 and it moves ;)
