Stage 2 questions

[Rdubya]

Hey there, I have a 2006 Polo Gti with the following mods:

APR stage 1 tune
FMIC
K&N air filter
TIP
3 inch down pipe
2.5 inch exhaust system
High flow fuel pump
Relocated battery
strut brace
rear sway bar
SAI delete etc

I’m interested in progressing to a stage 2 tune. My questions are:

Should I upgrade the fuel injectors? If so, which injectors should I use?

Should I get a custom tune? Are there any reputable VW tuners in the Newcastle area?

Cheers,

R-dubya

You're best to ask whoever does your tune what the required supporting mods are.

From your list of mods, you are already at stage 2 on the Polo. Stg 2 is reached when you change the downpipe (and optionally the intercooler).

From APR there is no Stg 2 tune. The only thing they will do is code out the check engine light created by the high flow downpipe. If you are not seeing the engine light on all the time, then it has already been done (or a spacer has been inserted for the O2 sensor).

The next stage is 3, which involves a bigger turbo. That will require a Stg 3 remap. Pick a Stg 3 kit (typically bigger turbo, possibly larger injectors and a high flow fuel pump + bits to make them all work) from the many out there, best to pick a kit that has a tuner associated with it. APR does/did at least 2 different kits and they should charge less for the tune as an existing customer.

Note upgrading the injectors on the stock turbo is a waste of time. The stock turbo cannot boost enough to require additional fuel. You only need injectors on a big turbo upgrade. Note Stg3 has different size turbos, so not all will need injectors.

No need for injectors unless you are going with a bigger turbo.

To make the best from the hardware you have I would recommend that you get yourself an intercooler. Look at Airtec on ebay, be sure that you pick the one for the 1.8T and not TDI!!

If you are feeling flush and get yourself a Littco 280 turbo, 550cc injectors and a 3 inch MAF. You could possibly see close to 200kw at the wheels.

I can help you with a stage 2 tune, if you have a windows laptop and buy a cheap OBD cable off ebay.

You should read my build thread too if you haven't already. Gavin's cheapy but getting more expensive GTI
