I'm not planning to tune the nuts off my coupe.. not at this stage anyway. I'm just looking for a bit more power and more importantly to make it a bit more smooth throughout the rev range as there seems to be flat spots at the moment.
Funds are limited, I have done the derestricted box, vectra air intake and panel filter. Would the pre cat mod (and possibly exhaust) be a good first option? I might not do anthing else to the engine for a good while so want to invest my money wisely and a remap doesn't sound like a good idea for starting off from what I've read.
Should the pre-cat help to smooth out the curves a bit? Also, does it make the car much more noisy?
Thanks for any help, I'm still getting to grips with turbo ownership.
