want to get more bhp from my 1.9tdi 110 seat leon se. was thinking of a tuning box to start anyone experienced these
 
I had a remap done, quick, clean and effective. Went from 110 to 143; the drive is so much better and more responsive.

A tuning box is far more obvious if you ever have the misfortune of being in an accident and you haven't declared the mod to your insurers. Also the box comes with a stock map, many remaps will be customed to your needs.

I had a tuning box on my old passat 110 tdi and it went well. Fitted really easily. Took bhp to 140 and torque to nearly 230.
The only fault I would note is that it became smokey, but other than that, great.
I also fitted an open cone k&n 57i which gave a nice whoosh, whistle noise but did make the engine louder on tickover...

Did either of you have any problems with clutch etc or any other mechanical part after fitting this.
 
Most peoples preference would be a remap, because a tuning box just doesn't do the job properly. Correct recalibration of the software will keep the engine running efficiently with the right AFR's and temperatures, meaning less problems with VNT's getting clogged up, better fuel economy etc You won't get this from all tuners, but if you choose wisely you won't be disappointed.

Clutch and mechanicals were fine..
Fitted for over a year with no problems, but I did notice a small leak develop from the rocker cover before I sold it.
Whether the increase with internal pressures caused it, but the car ran sweet. Thought about a remap but they were expensive at the time, so I went for the cheaper option.
If I had the choice now, I would prefer a remap from a reputatable company.
Just piece of mind..

My remap was done with the car having over 95k on the clock. Now at 120k and no issues I would attribute to the remap. Without hesitation I would have another done if the need arose.
 
Another way of gaining a few bhp is getting rid of the std exhaust & going decat as you don't need a cat on a diesel anyway
 
i put a tuning box on my old mk4 golf gt tdi 110bhp it had 145000 on the clock. and within a week or two the clutch was gone. i changed the clutch and it was fine again. they do tend to smoke alot and after a long drive its time to clean the car again.
 
No,you can also change back box to a single 1 as this is a restriction on power too

Diesel isnt like petrol,loosing a silencer & cat dosent make much difference to loudness :

Okay cheers mate I'm gonna do some before and after pictures anyway soon. Need some alloys but dunno which ones to go for. So I could alter the exhaust and change to a cone filter or maybe an upgraded panel filter and see what difference it makes could place to start I reckon
 
the standard filter is fine i wouldnt bother changing it, get a remap done, i got mine revo'd, and i am going to get the back box removed at some point.
 
Wouldn't it smoke way more with a decat.... I thought the idea of the cat was to reduce the emissions and smoke issue...

De cat wont do anything power wise, you can gain maybe 5hp on the PD 150 removing the backbox. Cone filter etc wont do anything either, even if you had no air filter at all. Get a remap, get bigger injector nozzles, bigger turbo and a remap or something along those lines.
You wont smoke more without the cat either, your emissions will be higher but nothing you'd notice and the car isn't louder.
PD 150 intake could help with a remap as it allows better air flow but your injectors will still restrict how far you can get first then the turbo.
