Hi,
I have mapped a few 1.9 tdi 105 with hybrids, you will need a decat, intercooler and stronger clutch as a must. 320 ftlb and 185hp is possible with time spent mapping it correctly on the dyno. Our stg2 makes 275 ftlb and 155hp without the hybrid on a stock engine and with cooler and decat 165 and 280 is achievable. I would also advise new seals and clips for all of the boost pipes before mapping it, and give them all a good clean, we spend longer fixing boost leaks than actually mapping on most hybrid TDI setups.
