First of all wtf did I just attempt to read? If you want help you need to post up in an educated and somewhat coherent fashion.
And no it sounds like you just need a tune bad. Big injectors will make the car run really rich, and if not tuned properly can ruin the piston rings by washing them with fuel. A litle cam tune wont do crap on an ms3 seeing as its a huge cam. And there's no way you fit a 94mm tb on an ls6 intake without a huge adapter. In which case do yourself and the tuner a favor and put a stock ported one on.

) If no codes are showing, you likely just need a tune. What you have done I would consider significant modifications and the car needs an immediate tune, especially with bigger injectors. To be safe, most people wait to install the bigger injectors until they are at the dyno shop. Thread Starter

Yes im gonna get a scan tool from autozone lockdown99ss and see if there are any codes it just revs super slow and dont want to be on the dyno trying to trouble shoot stuff the check engine light is off
Sounds good keep us posted hopefully that solves problem like suggested getting car tuned is good idea that will expose issues and make car run better as well good to invest now with mods cause it be safer and run better as well

You shouldn't even be letting it idle with a bigger cam, injectors, and no tune. Even if it was tuned for a smaller cam. The bigger cam will make it run richer at idle and the bigger injectors will amplify that. You're going to screw things up in a hurry if you don't get it tuned.
