right, as you probs all know, im new to the forum, and im new to vw's :).
i came from a line of fords and peugeots, and none were turbo, so this is my first turbo car aswell.
i have done a search for all the info, but it all seems so vauge, so was wondering if i could have some help in this topic?
that way, i can refer back to this topic for help :)
anyways, onto the questions.
I have an AGU engine, and it has been remapped already, and apparently is running approx 195bhp, but no print out of power.
I have proof of the remap though, it had a Custom Code remap, and was done at Midland VW in Cannock, Staffordshire.
The car also has a CAI, which im guessing means a Cold Air Induction!?
It goes down into the wheel arch behind the bumper
i have a few things planned for a stage 2:
replace re-circ valve with Forge 007p
FMIC kit off ebay
full exhaust system (not sure which make yet though)
i have been looking around, and have been pricing up exhausts, and so far, Powerflow have been the cheapest.
i was quoted £460 for a 3" bore downpipe from the turbo back, with a inter-changeable decat pipe, going into a 2.5" bore from the cat/decat back, with a tip of my choice, or £640 to replace cat/decat pipe with sports cat.
which would be more beneficial, a decat pipe, or a sports cat? i realise ill have to change decat for every M.O.T. :)
will this give me a noticeable gain, and be much better for a Stage 2 remap?
will the FMIC give me any noticeable gains?
is there anything else ill have to do to make the most out of a stage 2?
i dont really wanna upgrade my turbo, unless i really have to.
anyways, i just want your advice as to where to go next in terms of power, etc.
oh, and 1 more question, the person i bought it off told me to keep the car ticking over for about a minute before i turn it off after driving it? will this improve turbo life? if i dont do it all the time, will it cause damage?
i know you probs get these types of questions all the time, and are probs fed up of answering them, but i am grateful for any comments and help given :)
Thanks, Matt

you are already at the limit of the K03 so nothing you do will make any noticeable difference
The only way to get a good hike in power will be to change the turbo for a K03s
all of the other parts you have listed you want to change are good bits to upgrade. If you're willing to change the pipe over every MOT I would say a decat is the one to go for as the AGU doesn't throw a wobbler with one fitted.
As for a remap, speak to Nick or Ben at R-Tech on what you could expect from one of their spec-03s remaps especially for the AGU K03s combo :smiley:

thanks wazzzer :)
sorry if im just being dull, but is a K03s a straight swap, or is there other parts i need to do the conversion?
if i do the K03s conversion, and do everything i want, exhaust, FMIC, forge 0007p along with a stage 2 remap, what power would i be looking at roughly?
-
I think around 215bhp is a realistic figure, I may be wrong though.
yes K03s is a straight swap, you really need to get a silicone TIP at the same time though as the standard one is very restrictive.
There's a list of bits you need to renew when you fit the K03s in the maintenance section I put up a while back. Budget around £200 for the K03s, £50ish for gaskets and around £70 for a TIP (THS make a good cheaper alternative than Forge for them)

wot is tip? Sorry for being stupid?
