Nothing is loose either checked the intake tube on the SC and car will not build any boost, Will spit and back fire?

Now I am not an expert by no means, so take everything I say with a grain of salt. If it is spitting and backfiring it makes me think that there is an AFR problem. So the first place I would look is to make sure that there are no leaks anywhere. I know you just said that you checked and everything was tight. All I can think of is an air leak, bad maf sensor or something along those lines...

i might be wrong but some cars once u jump it or bat is unplugged willl reset the tune and since u have a custom uprev tune it might have just flashed back to stock

I was thinking this also. I have Ciper, is there a way for me to see what tune is on there, I know I can still do the map change and get my"Valet mode" to work,

True I was thinking bad injector or pump. The start issue was the samething I have with the Stillen can tune, But the car would atleast drive?

im not sure but try valet mode

I did it works. I was thinking to reflash my car with my tune again? My tuner is emailing me my tune? I have Ciper and the cable from Stillen, Do I just download the •Osiris Tuner Installer.exe (17.2 MB)
which I just did plug my laptop into the car and flash it?

that should do it, if the tune is the problem

If it just started all of a sudden then I would suspect cam timing sensor and/or fuel. You still on the stock fuel pump I presume? No CEL?

check your spark plugs

Most don't loss there tune just because the battery is out there is a small battery in most cars to keep the ecu
If it is the tune then that small battery my be the cause if it's bad

Yea man started right after I jumped it.. I jumped and drove it right away, drove a little weird, did not get on it at all. Meet my client at the gym went to my house changed a hot water heater for a tenant the tried to drive home all in all after the jump I drove it for 30-45 mins total car got worse every minute. I can take logs but do not know what I'm looking for :/.. Yes BTW the Stock pump jusdt rewired, The Stillen kit stays on the stock pump. But no CEL,

even if was out for like 8 hours, I parked the car at like 9pm and went out this morning at 815am.

Hmmmmmm, are you sure you running your stock fuel pump and not the Walbro 255 HPFP. Because everybody else's kit came with a new fuel pump.
