So had the Superb put on rolling road to check power after catback exhaust and JB4.
Car did 3 runs, i switched between map 1 and 2, didn't bother with stock.
Not going to lie bit disappointed but still happy i guess....

Isn’t 330 hp about what most tuners give as an increase with stage 1, but I think the torque figure is pretty impressive. As an earlier post on max torque for which gearbox suggested (400 Nm for the DQ250) that’s getting on for 475 Nm!

I think you're right, they normally state 330 upward but seen claims of 370+ from stage 1. That was my worry too when i was looking into tuning options. Found quite a few posts of people stating no issues with figures close to 500nm and over. These boxes have been around for long time and been tested thoroughly. Bear in mind that 475nm is a max torque so you not actually using all of 475nm all the time. I think if someone was booting it everywhere and using launch control from every traffic light then that could be a problem. George from JB4 who does all the mapping and aftersales assured me that in years of selling JB4 boxes there was very few complaints about dsg issues after box install. Only time will tell i guess but had it on since April and so far no issues....

Check this out where i asked about whether dsg tune needed for jb4

 

On the Steinbauer tune, I would be expecting 332hp and 420Nm or a least that’s what they advertise the increase is. It’s a similar set up to the JB4, plug and play and removable if you wish to sell on. You shouldn’t have any issues with the torque if you’re not doing launches every 5 minutes. @newbie69 has a good handle on these things and from what I can read he wouldn’t be too worried about those levels through the DQ250 gearbox.

You posted pictures from the Dyno run, but these are ‘only’ figures, can you feel the difference, are you happy with the feel or was the lack of neck snapping acceleration the reason you wanted to check things out? I would guess at that level of torque, mid-range pulling power would be really noticeable.

When i first installed the Jb4 box i could feel or thought i could feel difference even on normal D mode driving with car being more responsive but that could have been just a placebo effect. If you stay off boost the car feels pretty stock (forgetting the exhaust note) but once you push it and it comes alive oh yeah...it definitely feels quicker, more aggressive and just wants to pull. I just wanted to have bit more power and noise but keep the car more discrete, none of my previous cars stayed stock so i guess it's just a bug i caught 😀

Is that 330bhp at the wheels, Mario? Did you install the JB4? If so, how was it?

No mate its at flywheel, and yes i have installed it myself....fairly easy but had access to ramp which made it lot easier....tapping into O2 wire was bit stressful but easy enough....then running the obd cable through firewall took some time but easy as well

I got the lend of a racechip tuning box and installed in it my 2.0T 220bhp for a short while.. took it to a local rolling road and it put out 289bhp and 350 Lb/ft..  I run on super unleaded also..

Cheers mate. Can you explain the tap into the O2?

There you go, it's easier to watch on video but basically you need to connect one wire to your O2 cable(normally red wire) with posi tap connector so the box can read data from it as well

Perfect, thank you Mario; I really appreciate it.

No problem mate, hope it helped a bit

Sounds about right for Map2 on this engine, and I've seen up to 350 with custom Map6 settings if you can bother with tweaking and measuring.

I remember there was a noticeable difference when I went from JB4 to REVO stage 1, not night and day but definitely a keener pickup and pulling all the way to the limiter, which also translated to better acceleration times.

Was that difference over the JB4 worth the remap's cost? Not really unless you're a sucker for mods and have the power bug if I'm honest. Even less so if you consider the voided warranty with the remap. JB4 is a no brainer on these cars imo.

I've stopped caring about dyno figures (curves are still nice to see and often rather telling of the map's quality), more relevant would be some 100-200kmh and 1/4 mile times if you could get your hands on a 10Hz GPS measuring device (DRAGY, RaceBox etc) if you'd like more context of how it fares against other stock cars.

Was thinking about tweaking it further on map 6 but considering where i live the weather and conditions change 3-4 times a day would be pointless. I'm pretty happy with the feel of the car and way it lays the power down. What i noticed tho is if i push it to redline it now upshifts later. Before jb4 it was 6000rpm now its 7.

I might consider adding turbo inlet pipe but pay bit more for branded one and maybe upgrade intercooler...might.

@newbie69 would you say my torque figure is still healthy for gearbox at 475nm? 

Haven't launched the car since i had box installed so would be intriguing to see how it feels now.
