It's the chiptuning which provides all the power increase. I took two measements to prevent a turbo meltdown / to give the turbo a longer life. The exhaust gasses are getting pretty high if you increase the turbopressure with chiptuning.
First fitted a bigger downpipe (and a de-cat included) and second removed the standard IC and fitted an FMIC. The FMIC provided 30 Celcius degree temp drop @ full throtle, and gave the opportunity to inject more fuel, so more power.
My car @ 210 bhp doesn't smoke at all, btw.
230 bhp is possible, just by increase the turbo pressure further. But I can't take the risk. I need my car for my job and I haven't another car. So no space for experimenting further for the moment.
Heat is not the only problem. The standard clutch and flywheel can't really handle more than 400Nm. It should handle +/- 450Nm to get near of 230bhp. The dualmass flywheel is a really expensive part, 700 euro, and don't forget the fitting hours, 350 euro.
In Holland there is a 156 1.9 JTD (115pk) with 160bhp, just by chiptuning. But he will need a FMIC before the spring begins / outside temp rises.
I would recommand FMIC, bigger downpipe and do another chiptuning, or accept the 150 bhp and spend your money at other things. If your car smokes then you can decrease it by fitting a replacement airfilter or maybe the CDA.
