As above really, I plan on remapping my own car so want cost effective hardware/software to begin with. Car has gt2560v turbo, very large intercooler decat and will be getting larger injection nozzles soon.

Thanks for any help

Hi.
I used mpps today for my e46 320d (150bhp)
i didn't try it with lov voltage (under 14V) so i went and buy an charger which can do slow, fast and start mod...
fast mod wasn't enough (20A) so i used the start mod of the charger, it was ok!
I was able to reed my ecu and i sent it away and got an modified file in one hour, load it up and went on a test drive.
the map was ok, good acceleration, im quet happy! So if do the requirements mpps is a good tool to remapping!
I used this kind of tools first and reemapad car first and was easy, but i was stersfull till i've finished... :)
Find a file tuner who is good and offering file service by emailing it!

I always take a second car and give booster for programming. By this I have always over 14V. Already have a few vehicles easily programmed with the MPPS
