1.9 has very high fuel injection (80mm3 from 1800-4200rpm), duration maps increased by 15% on top of that, quite high boost for stock turbo. AFR is set very low, so this should smoke quite a bit. Also I would expect a bit of flywheel judder at low revs since injection is so high.
SOI and fuel pressure are not optimal...
All in all very aggressive map... not safe in my oppinion for a stock car
2.4 is just "percent tuning". 10% increased injection duration, 4% higher boost everywhere, 25% higher torque limiter from 1000-4200rpm, 5% higher fuel pressure. Stock SOI, AFR set to 13.5:1... In other words, bull**** tuning.
I guess perfromance wise should be quite OK, but with quite a bit of smoke, and it could be done better/safer...
