Hey guys I just got my car tuned and made 345whp and 345lbs of torque on 25psi on 91. Stock block and evo 8 turbo with 10.5 hotside. I pretty much have all aftermarket bolt ons. My tuner used evoscan. Sometimes when I go full throttle my car has a hesitation and sputs a bit then takes off. I don't have a wideband in my car though. So I can't see what she's doing. Like it farts a sec then hauls ***. Any suggestions?
