would taking off my air filter and intake tube to the turbo throw off my tune? i used a fine screen over turbo inlet for open turbo. I also got my car with no dump, it just had a 90 degree elbow coming off of wastegate so i fabricated a long dump tube to get the bad air out of engine bay. I did both of these things at same time and when i took car for a ride it sputtered. which one could it possibly be to throw off my tune? I guess i should throw intake back on and see what happens.
