TBH the smaller PACE item isn't much cop. I would save the money and get a better item like the big Pace or a GRS. No point getting the wrong one as you will only have to spend more in the long run changing it again.

I'd spend some cash sorting the probs like the cable ties and sort the basics first:-

Exhaust
Air filter
Setup.

I would almost gaurantee a transformation in the car for you. If all is healthy you should see 160-175bhp which is nice and useable
