the car was tuned by the previous owner back in SoCal befre i bought it with an open source tune, he made 295 whp and 260tq
with this same exact set up i have added a blow off vaulve which i believe leaks a bit but the car would run fine with it this problem just started about 2 weeks ago.

the first thing that comes to my mind would be to check the boost line to see if it's properly connected, probably came loose.

oh check all hoses and lines to make sure there are no leaks anywhere.

that's all I got to say, ha

Or anybody know of a nearby shop close to modesto where they can do a diagnost on my car with a good reputation at a cheap price?

Did you put a vent to atmosphere bov on that it didn't have before? If you haven't been tuned you definitely need to. Did all this start after swapping the bov?

It sounds like a leak or potentially a tuning issue. I'd have to check the car out in person to get you a better idea of exactly what's going on. Give us a call if you'd like to schedule an appointment.

Thanks
