Any issues in running this on a GTA ? No reason why they should be any different ? Also which would be the later version , Renix or Seimens ? They have different ' chips ' in the boost area on the board .The Seimens is marked F1
The 25T ecu runs more advance low down, less laggy, but doesnt seem to have the punch up top, but then this could be just a 'feeling' thing due to the better power delivery. Im running on a car at the mo.
