I've owned my Focus ST225 for well over 6yrs now , sorry I hate the xr5 name given for us lonely Australians . Over the Christmas long weekend (3wks) I installed a RS intercooler, a 3in Mongoose full exhaust ,a better air induction system and removed the symphoser which usually fails . The car sounds and drives much better now .
I want to unleash more power and bought a second hand Dreamscience stratagem flash tuner but found out that the previous user didn't put this std tune back in, rendering the unit kind of locked, yet I can still still fix check engine light , not that one has ever come up .
I've emailed Dreamscience and they want it sent back to UK and then they can cancel the previous cars info for a sum of £127+ postage each way, is there another way or website I can access to do this myself.... There's gotta be some tech heads on here that might know. If no joy, it's going back to UK to fix , I'm just seeing if anyone can help , thanks in advance 👍

Try asking INJECTRONICS PTY LTD ..........  I think they're in Dingley or Dandenong

Thanks Beevee, I've emailed them and will hopefully hear back in a day or two.
Cheers 👍
