    The new next generation twin turbo diesels should overcome this problem.

    The 1.9 has always been the same, catch it in the wrong gear at low revs and it takes an age to come on boost.

    But as said by 98vectra, the TT will solve this. The Saab 9-3 1.9 TTiD is fantastic to drive.

    that all due to everybody going to the wrong company for there remaps

    but i know where there is a man that will map your car on a 1 to 1 as its on the rollers your map is made to your car ,,takes him about 3 hours and your car does around 15 runs on the dyno as he rewrites the map for your car .

    not cheap but its the best way to go,, but the again it less than the eds software and bsr

    or look here for the best

    I must admit that now my bank is empty and I have a new inlet manifold and EGR, mine doesn't feel like that graph suggests, it pulls for low down well now, certainly lower than 1700rpm....

    Mines wasnt the best at low revs but fired a tuning box on it and it makes a big difference, anything above 2500 revs and it pulls extremely well
