   hi i am thinking about gettign a turbo kit for my vtr from Dp-engineering, but they recon that you will need to remap your managemant or get a new chip remap, if the kit isnt going to generating loads of power couldnt the kit be used as a bolt on and with ecu mods,
   
   if ne one has bought a turbo kit advice would be very helpful thanks

   Whats the point you may aswell sort the management out if you've gone to the trouble of fitting a turbo.

   but its alot of hassel because i can fit the kit myself as i am a training technician, but the remap will cost me lots of money and i will have to take it away to a garage etc.

   I'm with you but you may aswell use the turbo's full potential for the £400 the remap will cost.

   You would need something for the extra fueling, either an external injector controlled by something like an ERL MF2, or a VTS fuel rail with uprated injectors and a remap or standalone ecu.
   I was running 0.5 bar on my T2 for awhile and still needed extra fueling, if you’re going to bother turbocharging your car you might aswell do it properly, don't cut corners.

   cutting corners = bang and then more money

   surely if you don't sort the management you'll run it very lean. Which will cause a massive bang and the end of your engine. If you are going to do it, as said above, do it properly. Power is only good if its reliable.

   at the very least you need an Mf2 and also a sigcon (both from gmc). Mf2 to run the extra fuelling and sigcon to fool the standard ecu into ignoring boost ( you can't just remap the standard ecu as it can only recognise vacuum and would shit itself if it detected boost).

    That's the actual term that appears on the fault code. Proper management is the only way. The poor little MM unit is just not cut out for boost

    We have a car in at the moment that had a turbo kit on with no fuelling mods.
    
    When you first drove it it would pull ok, but you could hear detonation. But the knock sensor would do its job and then pull loads of timing until the car was actually slower than when it left the factory. Our wideband wouldnt even read the AFRs it was running that lean. Which is obvioulsy extremely dangerous.
    
    We then added a standalone KMS unit with 490cc injectors plus a large front mount intercooler. The results were a constant 200bhp and 180lb/ft torque, with driveability and reliability.
    
    For your situation even an MF2 with an extra injector + MAP sensor would suffice.

    You cant argue with that.

    Worth noting that Sean's Supercharged VTS gained 40bhp by going with a KMS (from Carworx) over the MF2. I went out in that on Monday night, was impressed with how factory it felt, if citroen had ever made a 230brake supercharged Saxo it would probably have driven as Sean's did. They may have added a diff to make it go around roundabouts without destroying its tyres though
