    07 Cadillac STS V Tuning help

    I recently purchased an 07 Cadillac STS V I have made allot of mods and need some tuning help possibly remotely. I'm new to HP tuning and don't want to mess something up I've made some changes so its reasonably drive-able but its no where near releasing the beast, I've made the following upgrades. 2.35 supercharger pulley, 60lb Siemens Deka EV 1 injectors,Frozen boost heat exchanger, race cats, x pipe, flowmaster super 44s, MSD fuel pump booster, spectre stage1 & 2, NGK plugs, 100hp NOS dry kit. I was hoping to find someone with possibly similar upgrades. I haven't even tried the NOS since I've upgraded to the Siemins injectors I know i need the fuel injector tables right so I don't lean out and burn something up but finding injector data has been tricky. I'm hoping that I might find someone willing help me out a little. I have tune logs and scan logs I'm happy to share and am willing to listen to advice that is helpful while I learn what I'm doing. I've talked to allot of local tuners and shops and they keep telling me we don't do that platform anymore.

    Hello guys. I am curious how the tune worked out for you. What size pulley were your running on the car as well. Thanks in advance.
