Mazda 6 CD 120 or CD 136 chip tuning

Hy fellas, I'm interested if anybody has any kind of experience in chip-tuning for Mazda 6, turbo-diesel machine with 136 HP (I'm also looking for tips about tuning of 120 HP machine!). As it looks that machine CD 136 is already factory tuned-up from normally 120 to 136 HP, I'm interested is any possibility to tune that 136 HP machine to some more. Please on help of any kind: links, tuners, prices, experiences... who, what, where! Thanx for any word of support or help!

Hi, I also own Mazda 6 136 GT and know that, it is possible to tune Mazda 6 136 to 160 HP. And it cost's about 500 eur. I 've done that tunning on my old Passat 1.9 Tdi 110 HP, and tuned it up to 140 HP. Your car will need 10% more fuel only when you accelerate, otherwise not,but the problem is that you will accelerate more, because of the new chip:). Car will accelerate a bit faster, but end velecity will be the same. Your engine will gain more torque(50 Nm more) and that's the reason why it will need more fuel. The original chip has been optimized(fuel consumption and torque), but otherwise if you change the chip wont harm your engine.
