hey guys for some resion my car recently lost power, i had my car tuned and then it was running like a champ and recently after that it felt like it went almost back to the stock feeling. after the tune it would hit 26 lbs and hold like 18 in every gear even first now its only hitting 20 in first and 2 some times it will hit 26lbs. could i have a boost leake because of the higher boost might have made my BOV leake or somthing? thats the only thing i can think would be wrong. i was also thinking the car could have rejected the tune but the AFR is still staying about the same it was after the tune, so if you guys think u might know whats wrong let me know thanks.

 

Sounds to me like the BOV is leaking, or you may have blown off a hose-clamp and your piping is leaking... check all the connections...

If that fails, search around and find a good shop (I Think CBRD might have one) that has a boost leak tester, where they actually pressurize your piping to like 35PSI to check for leaks.

 

Boost leak test time.

 

Of course, it could be something much much worse too. Like a melted turbine.... Failing Turbo... ECBS gone to ****...

Good luck!
