Welcome to the site!
Sounds like you got it covered. Can we see some photos? Why not start another project?

An FMIC and a set of new front tires.

well i would like to keep going on performance options... FMIC is what i was also thinking but any other ideas maybe bigger turbo if so what size and kind? Aeron did my revo program and told me to sign up for this site

depends on what you want from the car...the gt28 kits are nice and are still good for Daily driving...i think they make about 400 chp

have you upgraded injectors? I guess that will be a requirement for bigger turbo............ pictars pleazse

In Billings, I must have seen your car at some point, post some pics with an intro

You have stage 2 tuning - do you have all the supporting mods? I.E. TIP, DV, high flow cat or test pipe, FMIC...

It sounds like you have most, 4bar FPR, intake, exhaust...but I would for sure get them all to get the most from your tune before going to the next step.

A K04 is a bolt on mod with those supporting mods, but any more than that and you really should look at building up internals and beef up your driveline. A tune with a BT (big turbo...GTxx series) would shred the clutch, axles and puts enough power at the crank to start bending conrods and breaking cranks etc.

ya its silver jetta i am usually out mobbing around

i will upload pictures over my christmas break when i am home from Rocky

i dont have the FMIC yet and what you meaning by I.E. and T.I.P??? i have a high quality diverter valve if thats what you are meaning by the DV. i am looking at injectors right now any advice on what company and size to get??/

and mike thanks for the advice i am just getting into the tuner world... just grew up around muscle cars... sounds like i should just start beefing everything up internal wise connecting rods studs and tranny wise.... then go for the bigger turbo

THANKS for the help

I.E. is not a piece of hardware or a mod...

When you mean “that is,” use “i.e.” It is an abbreviation for the Latin phrase id est. Either can be used to clarify a preceding statement, the first by example, the second by restating the idea more clearly or expanding upon it.

TIP is a turbo inlet pipe - the stock part is restrictive, and the internal ribbing causes the air passing through it to be turbulent. So your CAI sucks more air, but it's still bottle-necked at the TIP. Kinda like having a big glass of water and a small straw; bigger straw will get you more water.

A silicone will be less restrictive and is smooth inside. Samco makes a great aftermarket part.

I guess what I'm getting at is to get all the supporting mods for your current tune, then go from there.
