Performance upgrades GTI

[bullsta]

Hi all.
I,m in the process of sourcing a DP for my GTI.
I chipped about 2 or 3 years ago and car has been trouble free.
I,m happy with expected gain with DP BUT........
Is it worth fitting a TIP and CAI to our cars with the KO3 in regards to power gains.
Also will I need a FMIC if the above is fitted.
Car goes great and I understand the Flash was the best bang for buck but curious as to real world gains other members have experienced.
PS it is my daily drive.
Thanks

Performance upgrades GTI

They all help, little bit here, little bit there. Personally (not a MkIV, but a 1.8T), I'd go for an IC next.

There are some nice CAI options, but not going to do a lot for power.

Hey Bullsta
On my MK4 GTI I have a 42DD 3inch turbo back exhaust with a Custom Code Stage 2. No need for IC or CAI at this point
It gives our MK6 a good run.
You can get a DP and cat , but to really benefit from the extra mods you need to up the tune.
IMO, leave it as is unless you do hardware changes and retune.

CAI does little more than make a cool noise.
2.5inch DP & high flow cat added about 9kw with APR tune.

I have a BMC CDA in the shed, if you are interested.

I have an SPM downpipe and stage 2 Custom Code tune, standard turbo - k03.
Considerable improvement over standard GTI setup, and still using the stock intercooler without issue

Thankyou all.
As said, the car goes really well as is but a gain is a gain .
The problem may be that Revo don,t do a stage 2 for my car, although I thought the Stage 1 allowed for a DP (I will check though)
Hey while I have you guys about, has anyone tried the N75 J. From the TT to the best of my knowledge and apparently lets the KO3 boost a little higher. Again not sure how my Revo tune will like it!

IMO a tune isn't so critical on a MK4 with a downpipe, it won't throw any codes beacuse of the high flow cat. So you could get one fitted and be missing out on a couple of KW.

A vented wheel arch liner will help some more air pass through the stock intercooler, I remember we did a group buy on here about 4 years ago and I got about 6 liners from Courtney (whiteVR6) and Seb (Bug_racer) at Euro Revolution, they were a good buy for around $75 each. The VW part number was 1JM 809 962 A

They may even have one or two still laying around.

You can do a ghetto hack job but the genuine article is a nice effective mod for not much $$$ and a straight bolt on replacement.

I thought you only went to a stage 2 tune if you had a k03s, intercooler, full exhaust, high flow intake?

How much of a difference between stage 1 and 2 for a k03 with just a downpipe?

I have quite a few upgrades..I can't drive my car in the wet at all now and first gear is also useless as is second if u come into it with any heat. Surprised how much traction issues the gti has to be honest. Makes me want to go back to rwd or give awd a go.

Would consider an lsd, but have heard a few horror stories and they are quite expensive.

I have a Skoda Octavia - 2L TSI engine with K03 turbo
APR Stage1 was heaps fun and a quick win upgrade
The mid range torque improvement was awesome,
but the top end was weak and actually worse than stock
(less top end power and slow to rev out)

I put a down pipe onto it and upgraded to APR Stage2
Only 20kw!~25kw more but power band is much wider/richer/cleaner,
pulls from lower RPM and the top end was fully cleaned up, goes hard
Midrange torque further improved - overtaking is a total none event now

I've master the art of teasing kids in Commodore's and Subaru RS's,
they think they will blow me away and undertake me,
I don't use all my power, just enough to keep my nose a little in front,
Great to see young kids getting hot and bothered and grabbing for gears
before having to bail out and stand on the brakes to avoid hitting a parked car

I have also added CAI and FMIC - no significant performance benefit

For VAG daily drives I reckon DP & Stage2 is all you need
It's highly effective from both cost and performance points of view

I thought you only went to a stage 2 tune if you had a k03s, intercooler, full exhaust, high flow intake?

Intercooler and intake have no impact on ECU program
(If you do get any gains from CAI the MAF and ECU will deal with it)

Check with your chip tuner - for APR (on paper) it's about 20kw~25kw but the real world performance and usability is much more significant

Yeah, I hear you...
FWD is a modern practical thing but it gets very messy over ~180kw
In really conditions I've actually reverted to the stock ECU program
Car is useless in the wet below 50km/h
Even in the dry, front wheel spin from standing starts in 1st is a pain in the arse
You just have to exercise a lot of self control and be super smooth

It depends how the tuner classifies their system. Phase 1 is for a factory std car, Phase 2 with Custom-Code always involves a downpipe + any other bolt ons. Phase 3 is a turbo change, although on the MK4 we have a tune for a K03s on the AGU, which gets charged as a Phase 2. For confusion to the public

Ended up going down the low key route noting my Tune
Just ordered the APR R1 DV and Dub's BFI Stage 1 Dogbone mount inserts
Taking out my Platinum NKG7 (2 yrs / 30k) and fitting the NKG Coppers in the 7 also (I step colder)
Be interesting to see how these plugs faired. I hear Platinum don't dissipate the heat but mine have been faultless.
Come to think of it so has my Stock DV!!! but hey who knows it could make a difference.
I'll post pics of the Platinums when I remove them out of curiosity.
Hoping I can fit the Dogbone mounts at home too
Cheers for all your help

If your plugs were holding heat or your DV was not working 100%, you really wouldn't know it unless you log it. The engine will retard timing if it gets too hot and the boost will be lower than it should be (without a gauge, you won't know).

Stock DV's are not designed to hold 20 PSI, I'd think about logging it next, see whats really going on.

Hey Noone I,ve never plugged the car into any Vag cable, except when I first bought it 3 years ago.
Seems to run fine but as you said maybe it could run better?
I should check out if anyone around here in Sydney has one.
Is there much I can do though really if I have a Revo tune?
