    cheap tuning for diesel?

    hi guys

    a friend of mine is getting an Astra van from work 1.7 cdti (i think).
    he was wondering if there are any cheap ways to increase the power. ie air box mod, boost controller etc..

    any help would be great.

    thanks

    Tuning box would be the best option, can be removed easily and gives best gains on the diesels. Also, the usual air box mods.

    Hi,


    the cheapest way is to get rid of the spare wheel - it is quaite heavy. but remember - new opel astra is a bit understeer car

    You can also fit intercooler from 1.9 cdti or de-ristrict airbox /however in my car it cause that "engine check light" appear - I suppose to protect turbochargers /.

    or visit Poland - here chiptuning cost ~260 pounds,

    regards
    1.7 CDTI

    well because it is a work van he doesn't want to spend to much so i would say anything under £100.00

    Thanks

    If it is a CDTi, then one of the "Caterman" boxes from Germany will do the job. There's a guy on the Vectra-C.com forum that sells them, about £60.

    Would this work on the 2.2DTI (22DTR) engine?

    All the tuning boxes that I have seen are approx £350+

    No, the DTi engines are a bit more tricky thanks to the VP44 pump with it's integrated ECU. Tuning boxes on the DTi engines aren't a wonderful device, as you have to hard-wire them into the loom - they're tricky to install, may or may not work, and don't give very good results if when they do work reliably. You're better sticking with a remap.

    I was thinking of getting something like the following for my Y22DTR
    http://www.dieselbob.co.uk/bobbox.shtml
    http://www.dieselbob.co.uk/ecotune_vp30vp44.asp

    The are designed to give a minimum of 20% increase in power and torque!
