Performance upgrades in order of cost benefit

[hiredog]

All,

Am i right in thinking that the order of performances upgrades for cost/benefit is:

1. Air filters
2. Stage 1 Remap
3. Exhaust
4. Stage 2/3 Remap

Air filters - is there a straightforward winner/recommendation here?
Remap (any recommendation near Leeds?)

Considering keeping my car for another couple of years (is up for sale) and going down this route, and just weighing it all up so any advice welcomed.

Cheers

Carl

Exhaust is 4th

As always, it depends if you mean just engine performance, or overall car performance, but here are my ideas in cost/benefit order for overall car performance (just IMO):

1. Air filters (ITG circa 145 + 20-30 BHP more with mapping)
2. Spacers (circa 140 and better handling due to wider stance)
2. Secondary Cat Replacement (circa 300-400 +20-30 BHP more with mapping)
3. Gearbox TCU remap (circa 550, faster shifts and raised gear change limit)
4. Stage 2 ECU remap (circa 1k, a completely different beast ! )
5. KW lowering springs (circa 600, better handling)

After these, you start getting into some more serious modding, but also serious HP:
6. WMI
7. Downpipes
8. Hybrids
9. Gearbox strengthening
10. Ceramics (or die) (arguably these should come after the stage 2 ECU remap, but here only due to cost)

Cat back exhaust in my experience only adds to sound, unless you go for downpipes and hybrids (will then assist making HP), so if it were on the list, I would add it as 6.5.

For visual mods + value for money, you cannot go past a Trups LED kit.

Merlin Motorsport for the ITG filters: https://www.merlinmotorsport.co.uk/ (ask for John and he will tell you the options).
or MRC

The first time I fit mine in 30 mins, second time 15 mins, and I ain't no mechanic either !
