Garethseries1, I can not find a conversion kit for the Sigma engine on their page. Are you talking about the Omex solution concerning the 4/4 Sigma 1.6 VCT TI?
If it exists, do they use Jenvey TBs for this product or their own developed TB upgrades?
Another question, have you compared the TB performance with a standard 4/4 or with one where the ECU was remapped?
