Hello I drive a 2011 genesis coupe 2.0t. I upgraded the turbo and am now fbo and tuned, really fun car. When I first got the new turbo on, I didn’t have injectors/fuel pump or any other mods really (besides exhaust). I remember while driving on the freeway, I would press the gas pedal at a constant rate (no boost) and the pedal would stop working almost, exhaust note changes, starts to pop loud when it doesn’t at that rpm usually. At the time I thought it was because I wasn’t tuned. Well I’m tuned now and this issue still persists. Sometimes turning off the car and back on helps. Noticed the issue after the new turbo was in and I switched to 93. Is this a solenoid issue? Wastegate? Fuel pressure regulator? Anything helps, thanks.
