Status: offline 		it must be getting enough fuel because it makes boost really good and has alot of power and doesnt sputter or anything. Maybe it has bigger injectors and i dont know it because it seems just fine to me. I was just wondering if that much boost is bad for the turbo/motor?

flamingpinhead's photo gallery 		17 is like the max for stock fuel system there. your injectors (04+ stock, or 03 S1) are only 577cc/min. if you run it lean, like you likely are, youll kill your motor. do you have a wideband? if not, i suggest investing in one, its much cheaper than rebuilding your motor.

no because without a return line and fuel controller you'll have some serious problems

I don't see a reason why you would need any fuel mods then. I spike the same and hold around 16 and I am still running really rich with 04/s1 injectors and a stock fuel setup....

Status: offline 		oh ok thanks for the info., i have a wideband gauge alredy in the A pillar that tells me if i am running rich or lean but i have to get some 2 sensor from some '90 somethin dodge stealth or some other dodge car to make it work i was told because the o2 sensor in the srt-4 is not compatible with it.If anyone knows how to make this work i would greatly appreciate some help thanks. Then i will be able to know if she is running lean or rich.

You will need an aftermarket wideband O2 sensor. I believe Bosch? I don't think a 90' somethin Dodge stealth will have the right sensor, probably a narrowband.....Which wideband gauge do you have?
