Well Jezz has done me proud.
The car has never run so crisp and smooth.
No more detonation and over reving
Jezz advised putting a new map on which has cured the problem.
He took some of the boost from the lower end and put it on the top,
No more kangeroo petrol and had Jezz not descovered it was detonating I may have had an engine to pay for.
I think he cut the power back a bit as well but it pulls a lot better and it is a joy to drive (At last)
But he has got a bit more torque!!!.
What a difference is all I can say.
I can't thank Jezz enough for what he has done and for looking after the car over Christmas/New year for me as I was to lazy to go and get it lol,
Had I know it would perform like it does now I would have walked to Newbury!
I can highly recommend Jezz and I know that there are a few of you waiting to see the outcome of this.
So go and get Jezz to remap as he knows his way round a Nissan for sure.
At the end of the day its personal choice and you must do what you think is best.
But I am glad I went the HDEV.
