Try using Shell 91 Shiv and Rob showed me that secret. I used to be all about Chevron. Now I'll go out of my way to find a Shell station. Agreed, try running 13.5 psi if fairly stock. I have great results at that psi on California crap gas.

Turning boost down to 13PSI and turning autotuning off seems to have made a good improvement. The IATs are really high, but keep in mind it was like 92 degrees in San Diego today, time for some upgraded cooling! Thanks for the tip on the Shell 91, I'll stop going out of my way to find a Chevron

I changed gas stations, and now using QT... not sure if you have QTs in Cali. Seems to be good, consistent gas. I used to use only Shell also, after poor experiences with Chevron.

I would leave autotuning on with aggression level 1. UT20 max 13psi IC50. Your inlet temps are really high. You should consider getting an intercooler asap.

@Shiv: does autotuning raise my IC?? I mean: if I set IC100, autotuning reduce and raise IC between 0 and 100.
If i set it on 50, can it go over 50, like 60, or it works between 0 and 50??

I'm planning to do some pulls with some config, i wanna try maxboost autotuned on IC100 and maxboost autotuned on IC0: on IC0 i think psi will be less, btw i think performance will be similar...

From my experiance when I was running Shell 100 or AGIP Blu 98 in Italy autotuning would always want to max out the boost. I think the octane rating on these are closer to 95 RON. The car really liked it compared to the green standard 95 gas (autotune would only give about 11psi on this). I limited the car to 13 or 14 psi for longevity even on the good stuff.
