Heres my setup...Stock b16 with custom turbo kit....t3/t4 turbo...Shunk2 Chipped ECU and a VAFC with stock injectors...I know I should change the ECU and get bigger injectors...anyway...My car is bogging at low rpm and then cleans up and boost fine...I reved it yesterday to about 8000 rpm....and ever since then its been acting fishy...Could I have messed up the ECU or injectors or caused damage to the motor?...It takes a couple seconds to start up now too...Please any info would help

 

Whenever my car starts acting differently the first thing I do is reset the ECU. Usually does the trick.
