Still having issues after chipping....UNI stage 2

[bora_1_8t]

Ok I'm still having some issues after I went Uni Stage 2. I have 380cc injectors BSR exhaust stock cat and DP, I have snow performance stage 2 meth kit with duel nozzle upgrade. So I'm having some bad cold start issues when I start it up in the morning the car starts fine and idles normal but if I try to give it any gas to take off the motor starts to struggle and will stall. I have to keep revving the motor like a old carbureted engine. To keep this from happening I have to keep the RPMs above 2k but when the engine gets up to operating temp I don't have this issue and the car works and drives perfect. I've tried doing a TBA that was no help and I have unplugged the MAF and also cleaned in still no help. So does anyone have any ideas on what to try. I'm getting sick of these issues I'm about ready to go to another chip.

Has it presented any fault codes?

Only code I got was P0606 saying a bad ECU but it cleared itself

Could be a couple of things. If you got a code for a bad ECU. The local tuner shop may have not flash loaded correctly and corrupted the file in your ECU. I would recommend a reflash followed by a TBA.

If the symptoms still remain, then start checking for vacuum leaks. Could be the PCV going bad (internal check valve), jet suction pump, or any of the related hoses and hard plastic pipes (which may be cracking).

I've been there. Had cold start issues, but no more after fixing several vacuum leaks.
