Want to tune better go reliable tuners. Donít later tune Liao ECU up Lorry.

Tune stage 1 liao then add all this to feel stage 1 at least 150-160 BHP if your is 120bhp.
DV+ diverter
Aftermarket air filter
Add pedal box for faster response to acc pedal.
The pickup from low to mid will improve. But donít expect much high end.

Tuning is to make the output graph as linear as possible but there is this compression point at the high end which will cut off high end.

Stage 1 is good enough, anything above that can buy better performance car
Does this apply only for forced induction cars?
What is DV? There are reputable people that say Cold Air Intake is pretty much useless and may result in engine trouble codes in the end.

Dv plus diverter help to recycle the air back as compare to BOV which is release into the air. So it help to prevent sluggish , loss of boost and remove turbo lag.

Meaning u are replacing the stock valve using this GFB DV+


Forget about CAI alone. there is no significant impact to your performance.

Unless is open air filter with downpipe , then straight thru pipe to your exos then u can see turbo difference.

Some cai give lean or rich air fuel mixture which might give poor fc or car stock air-fuel ratio will go haywire.

Yup thought CAI alone was pointless.

So this begs the question as to whether stock NA cars are worth tuning? Iím hoping to get 10-15% more BHP and more responsiveness at lower speeds.

Is the increase of 15-20HP significant enough for me to feel the difference?
15-20HP on stage 1 is too much... At best you'll get 3%

Have you placed your car in a dyno?

HOWEVER... car will definitely sound much better and for car guys, that will be more than enough

DQ200 rated to 250nm torque.
They already replaced the oil with low sulfur oil which apparently was causing short circuiting in the circuits.

the 1.4 tsi (148hp with 250nm) variant is already running 1.2 bar boost. so this is the safe mod limit based on OEM tuning.

no one will regret stage 1 tune cause it is the best bang for buck. Actual power gains (feel and actual test) versus $$$.

piggyback is not the best. Best is to flash the ecu. piggyback is an interrupter / manipulator between engine and ecu. Won't be as smooth as flash tune where it is a re-write of the software.
Good info. Thanks.

My mk 6 is custom tuned, sort of between stage 1 and 2.
I only change air intake and decat my exhaust.

Personally i feel got difference especially the pickup, but i'm thinking of going to do dsg tune as well, this will shorten the gap between gear shifts and less "tua" during low gears.
But that's low priority as i'm already enjoying the drive now.

Have fun TS!

Iím looking at BMS Andrew and Eurosports Calvin. Any experience with either?
Calvin seems a bit conservative whereas Andrew seems to deal more jap ride although has done up considerable contis.
Also spoke to monster but decided not to proceed.

Who is reputable for contis? Iíve seen people recommend happy dyno tuners. Iíve seen people recommend tuners who toad tune without any dyno result.

Ya i did at racetech.
Did downpipe 1st, then like not very shiok, few days later went back to decat the entire thing.

Now feels and sounds good, heng still can pass inspection.

i would recommend Eurosports. I have used him for 2 of my rides - both conti and never had problems. another popular choice will be Monster Tune, both are very experience in tuning VAG rides.
