Flash the car back to stock and get it running right first. The basic bolt-on's in your build thread aren't going to prevent the stock rom from working. That removes any doubt that it is tune related. Pop some pump gas back in it and start there. Then contact James. Depending on if CGS's file is locked or not, he may even be able to take a look at it.
FWIW if the car ran right and then all then 1 month later had issues without a tune being changed or updated then it is likely not software. Spark, fuel and air...
Used DTC's to know where to start looking. Check the plug and coil. Have spark? Great time to look at air and fuel. Check AFR to see if you have an issue in that department. If fuel, start and the injector and work back to the tank. If air, start and the intake and work towards the engine.
James doesn't do locked ecu tunes. So anyone with ecutec and a laptop can look at the files and correct things if needed be it local or not... if your the learning type you can even give it a go. A large process of me understanding this platform was watching his revisions and seeing what he changed in the updates between the 13+ files we did making my first one purr.
Looking at data is a valuable skill in determining where to start a diagnosis, something ecutek offers by the truck load. Go to the library if you have to and get some free books on ecu tuning.
