Tiguan IS38 and Big turbo upgrades

[Dose Pipe Sutututu]

It's not power that blows motors apart, it's torque.

If you have effective strategies such as limiting torque then you can keep motors together, an easy way is boost by RPM or torque map the tune as you will.

Ideally you increase boost once you go past peak torque, this essentially limits torque and keeps motors together. Another strategy is to be super relaxed with timing where peak torque is, less timing = less torque/power at that RPM/load point.

Ive been driving around with an on and off CEL that’s been a tad annoying. I’ve finally bit the bullet and changed my secondary O2 sensor and it seems to have rectified the problem. My mechanic swore he had never seen a shot O2 sensor after years of servicing/ modifying VWs so left that as a last resort change.

As an observation I noticed that the O2 sensor had a white coating when I was running the pops and bangs file vs. the expected carbon build up without the pops and bangs file. I might leave off the pops and bangs file as it does tend to draw a bit of attention, and a bit embarrassing when I’m doing the kids school drop off.

My latest file no CEL for 5 days. Usually comes on after 3 days. TOUCH WOOD

My pops and bangs are only on in sport mode, you drive around in sports mode all the time?

I've got a mild crackle in my Scirocco and that's only in S and M. In D it's "normal". I haven't heard of crackle maps causing issues for O2 sensors but I guess it's possible.

Good news about your CEL, fingers crossed for you. I tend to drive in sports mode, I might as well enjoy the car! Gave it a few calculated squirts today and whilst the HSV was spinning its tyres and fish tailing, the Tig just hightailed it out of there.....

Well done mate and welcome to the is38 club! If you get a chance try to do a 0-100km/h vbox or draggy run.

Are you planning any further mods?

[jcheung_23]

I think it would be my last power mod, car is already crazy fast! At the end of the day this car is not going to be on the racetracks - will be saving up for a second hand rs3

Maybe some grippier tyres when these ones wear out

Just a quick update.

IS38 Tig has had the first 15k km service. Clean bill of health from the local independent VW specialist with no check engine lights or codes. Topped up with some Motul oil/fluids and she’s ready to fly again.

I also took the opportunity to fit RS3 (ELDOR) ignition coils and an APR dog bone mount (version 1). I will provide a review in a few weeks after the mount has settled in, no noticeable NVH so far.

Let me know if your downpipe starts to vibrate with the dog mount. Mine is vibrating to the point it making me want to remove the dog mount and downpipe, or replace both.

Hi Inasnt, there was some NVH yesterday, but after about 50km it relaxed a bit and I really enjoy the sportier feeling. Steering feels a bit heavier and much more in touch with the engine/car, it feels more direct now with turning and throttle response is great. There is less lateral movement now, so I get less of the mechanical dsg/transmission sounds which is good. The APR dog bone insert is made from stainless steel so is a fair bit harder than the aluminium ones out there. For the money a great little mod with immediate benefits and sportier feel. There is no downpipe or other rattles, with minor NVH being added, which to me adds to the sportier feel.

Hi Inasnt, TheTig got his IS38, apr hardware and tune from Peerless, I went to VW Park. I’ve heard very good things about Peerless and the team so you should be in good hands.

Yeah that was me, Simon and the team have been great. Car hasn't skipped a beat since all the work has been done. Just over 24,000Km on the spedo now. Very happy with it!
