The car had some mods lowwer and upper s/c pulley change electric coolant pump upgrade Thanks

 

This is bad. Some problems with bank2. Since the trims are positive - it's an vac. leak on a bank2 intake or it is a faulty upstream O2S. Also, it seems that MAF readins are a little bit low, so i suppose that it's a vac.leak on a bank2.

 

With checking this i got 2 codes p0335 and p1230 cleared these and did not came back . Ive checked the sensor and fuel ralais earlier so the codes could come up when i looked at this so i dont think these are the problem so if you sit in the car is bank2 the left or right side of the car ? And a vac leak must be after the supercharger after that the intake split and go trough the intercoolers and injectors to the head. If both banks were not ok the leak would be at the supercharger or elbow ,throttlebody ,intakepipe , or am i wrong ? This trouble happend after a week i changed the chains an tensioners and rebuild s/c it ran good for a week but then got problems so maybe a gasket is bad could be but ive checked with carb cleaner for leaks but then could not find one. But this info shows there is something there.
