100% yes !

do you have ppp ?

if not you will need to upgrade the fuel pump and panel filter to get the best out of the map

dazmotaz

i run a 3" turbo back milltek system, k&n panel filter, ported headers and turbo, remap by andrew carr 345bhp / 340lb...

depends how far you want to go, im planning for 400 so went for 3".

keeping your downpipe with a cat back system, panel filter, fuel pump and a remap should see you between 320-330bhp

At the risk of sounding obtuse, I've got an STi and I put a blitz nur spec on it, I've never had it mapped and its been fine (could just have been lucky I suppose). The Check Engine Light hasn't come on at all.

I do know I won't be getting the most power possible out of the car though, so in that respect you could say its a bit of a waste.

So a full decat on an STI? have you fitted a KS3/knocklink? if you did you would want to have the car remapped, do you know what is happening to your engine running a full decat (i take it you have though you have not said so, if not and are still running the down pipe cat, its not too bad), but with a full decat your boost spiking, this causes det, that puts holes in your pistons and you can lose compression or even worse, hole/crack a piston, or it can be what normally happens and thats engine failure as the big end bearing has a tendancy to go due to the strain, but your engine will suffer for it....

Ah, my mistake, I do still have the downpipe cat. I haven't got a KS3/Knocklink (I don't even know what it is, I'm afraid).

I do want to get a remap done, as even if there are no engine issues, I know I won't be getting the best performance wise.

im deffo wanting a remapp not wanting to go too mad like 400 bhp just up to same sort of power as my old rb5 was running at 327 tec3 remapp and a p1 turbo think vf 24 uprated fuel pump brembos i have found on this car i have a banging noise as if some thing is loose on the rear diff axle both the shockers and mounts on rear are brand new do any of you lads know or herd of this before and what it could be

Sounds like the standard Scooby shock absorber problem. Is it on the left hand side rear by any chance?

www.phormula.co.uk good for modified cars
A knocklink is something similar that has been around for quite some time, the KS3/4 are more informative.

it is yeah but there both brand new shockers and mounts only done a few months ago it feels like somthing is moving on rear
