Question Boost Problems..........

Is it normal to not hit full boost til around 5k , i only hold about 12-13 psi until i get around 5k...? i was trifecta tuned but had to reflash back to stock to take it in to the dealership for work... Took it in because i was not making any boost what so ever. Got it tested for a leak and they said that they found a leak at the inlet pipe so they tightened that ... they said that my maf reading is at 3.50 g/s at idle which is normal

only mods are hahn intake, This is driving me crazy ... from what i remember i normally held 15 psi through all the gears before i got tuned WHATS GOING ON ! Needs to be fixed before i re-tune it !

Any ideas?

you're gonna get that from all of them. i suggest you do a boost leak test yourself and once you identify the problem then show them. they likely wont do anything without the car throwing a cel
