Jst back from rollers.


Stated 167.67BHP (170ps) 258lb/ft
Actual 186.6BHP 273lb/ft

The car is absolutely standard with 7.5k on the clock. More than happy with that, but question the gains stated by tuners.
 
maybe question the rollers!

Alot of others that went are complaining about their cars being down on previous runs at different rollers. The mate took his m3, and the one time it would rev over 6k it only made 297hp, alot short on the 343 it was suposed to. But a leon cupra made more power aswell, 252bhp.

Last year my W8 ran atleast 20hp down, and my CTR was down on power also. There were alot of people complaining that day too.

This unit gives 204bhp but more important is the tourque figure of 420nm :). Its a box which can be removed if needed before any work has to carried out on the car and it means you dont have to go back and get the car re programed. Downside, in the wet the tyres have to work very hard and they wear out very quick 2-2.5mm after 7k. Would I reccomend it,
YES
 
Anyone got any info. on how tuning effects the fuel consumption, seems that much of the stuff I am reading suggests there may be gains to be had there as well???

I know thats not what most people bother about when they are tuning but I clock up 20k+ miles a year!
 
I would forget about the fuel consumption tbh prwilf. Some say it increases slightly, most say it makes no difference. So all in all its not going to make enough of a difference to be concerned about :)
 
Now there is a tuning solution also from BSR. http://en.bsrab.se/products/t1245/

205hp 425Nm. As simple as plug & play. You can restore the original program and tune it back again whenever you want, if needed. And you can do it all by yourself.

I put a K@N filter shortly after getting the car and wasnt impressed so I took it out. The car has over 7k on the clock now and has a lot more grunt, so may give it another try. What do you think of the K@N unit. Has it freed up the permormance at the upper rev limit?
The cold weather is fantastic and the car seems to gain so much more power when its cold.
 
DPF is a filter that captures the soot which usually comes out the exhaust. It is only on the 170ps version engines (i assume as they smoke more) once the filter starts to be come clogged with all this soot, the ecu injects more fuel into the engine to increase the engine exhaust temperature to around 350 degrees where it then burns off the soot caught in the filter, this produces a whiteish smoke/powder.

This makes the engine cleaner than ordinary non-dpf engines and they don't produce anywhere near as much black soot smoke all the time.

The downside, is increasing engine power increases the soot released from the diesel which means the filter clogs quicker / harder / faster so may not clean properly therefore clogging the engine and a dealer fit of a new dpf ££££'s

Remove the dpf, and you'll get a shed load of tuning options as you don't have to worry about soot output, however the dpf is linked to the ecu quite well, so its not something cheap/easy to remove.


How often does the dpf kick in, does it use more fuel, i have the leon fr tdi 170 and have noticed the change in my power recently , do you think its to do with the dpf , any help plz
 
Thats about right , if your pockets are deep then you can follow devonmikeboy power outputs for the PD140 base unit >350hp. My 170 produces around 202 - 210hp, I have come across threads from Dutch tuners that have got around 280/290hp [SEAT racing Leon diesel produces around 285]

do you have any links for his diesel tuning >350hp. that has perked my ears a bit. if i could get a diesel upto the 280+ region then i would definitely consider doing it. the main reason for me not liking diesel is the limit on the power increase once stage 1 mapped.
 
There is no problem with remapping them but you can only take them to 195bhp unless dpf removed, if dpf removed you can get up to 220bhp.

Iv got a fr tdi 170 , would any1 say to get it remaped to 195 bp, or will it cause problems for my dpf, any help plz
 
Would you say to remap my fr tdi to 195 or will it cause problems to my dpf
