Hi Guys / Girls
I have a silver 05 SRi CDTi 150 pre-facelift. I love the car to bit but the only few things I wasn't 100% on are:
- colour, I like the black or dark grey
- the facelift model has really grown on me
- I like the sat nav
So, I went and bought a black 55 SRI CDTi 150 sat nav - facelift last week.
The handling is significantly surer than the pre-face which is great.
However the engine is huuuuugely disapointing compared to my pre-face.
My pre-face was going like a rocket.... CR1 @ 21/22 turns and K&N. Turbo spooled up very quickly and nice loud sound, and very responsive from throttle press at 2000 revs all the way up.
So , I swapped the CR1 over and the K&N from old to new on sat and the car and I'm pretty unhappy. I was expecting it to be the same as my old but the turbo lag is huge. Once above 2500 revs and the turbo spools up it isn't too bad but there is about 2-3 seconds of lag compared to my old one and it is hugely frustrating.
I tried the CR1 on 18 turns and the same as before (21/22) and makes no difference.
How can two of the same engine designs/sizes be so vastly different? I can't even hardly hear the turbo spooling up on this new one. The old one sounds awesome.
I am at the point of wondering if there may actually be something wrong? Does the engine management take time to adjust to filter/CR1?
I am also considering selling it on and keeping the old one (which I still have)?
Any one offer any advice or shed any light on this please?
