Ok so heres the deal:

Got an sti2 with microtech ecu (from Andy F), ported headers, walbro fuel pump, fse reg, full 2.5" decat system - open neck downpipe, TD05 90 degree entry, earth mod, AVCR boost controller running 1.2 bar, KL, LL and usual gauges, sti panel filter. Standard 380cc injectors and 3.2 bar on reg with vacuum off.

I have been offered a brand new HKS fmic and fully wrapped stainless headers (not equal length) and flexi up-pipe and also i would purchase an induction kit.

My question is should i buy just the fmic or both the fmic and headers and also which would be the best induction kit (not running a maf just map).

I am looking for good torque and not just outright power.

Please help me with advice!

Hi Stuart,
I noticed the bigger improvement once the HKS headers were on, and combined with the HKS fmic i had on, there was a vast improvement after remap.
If you can afford both, go for it.

Saying that, my headers were equal lenth, so, not sure the benefit the stainless ones would have over your ported ones.

I opted for a Blitz sus Induction kit...got it lying here if you want to try it.
