Not right now, as when it matters, when I'm driving on the open road it's great and I don't see the heat soak issues.. I'm at a catch 22 with this one.

Yeah, I've never seen Temps like that before. Unless the piggy back is given false readings but I doubt it would be doing that or even hooked up to that.

OK... I have to hold my hands up, I have made a mistake. I thought I had carried out 2 stock runs on the dyno and 2 runns with tunning box on but, I had never turned it off, actually I had not connected the remote switch properly so the system was full power.. Here is the dyno showing only the box on

None of the runs were stock... The unit was permanently switched on.. The remote switch to turn the unit on off was not connected properly, my bad! So the 398bhp is the first run the rest I was suffering heat soak, seeing Temps up at 80deg c

Probably you should go back dyno it before you have IC & DP.

What revs is that pulling at those speeds 60-80mph? seems like big torque increase in that band.

So I done some more runs and this time I was in 4th...

4th gear 60-80mph

Stock was 3.1sec

Stienbauer was 2.7sec

That was with a full tank of fuel too.

I also used my own stop watch this time just to clarify the meter I was using, it seems that the app is a little erratic so I went with the stopwatch times.. I done around 4 pulls with tune on and 4 with it off.

Would be good if someone who has a tune doing some similar tests! I also just read evo mag and that tuned 40-60mph time in 4th that I pulled is the same as the new Audi tts time.
