Car Not Boosting As It Should :(

[blackxr50]

hi guys I I recently got my car tuned by blue power, it mad good power and was running 14 psi

but the past week the car is lacking power, I looked at my boost gauge and every time I boot it it only goes to 8 psi and won't go over ,

I preformed the boost solenoid maintenance but no difference

can anyone help me on where the problem might occur from :(

What cat is it running and have you checked piping for boost leaks?

The factory joiner at throttle body is known to split quite often on F series.

any vibrations when accelerating? does it accelerate smoothly? have you connected your xcal to check for codes?

have you done anything since the tune apart form the boost solenoid clean?

Check the hose clamps for loose hoses? Not unheard off where mechanics don't tighten them up enough

Recently had an episode with my radiator hose clamp on a different car I took in for service after they did a radiator flush - hose came off after 2 days of driving

How do I check if the piping has a boost leak?

I dunno how to use the sct tuner to check for faults also is it safe to drive :(

The car accelerate smoothly but as I said on boosting to 8 psi

[Paulie2256]

just plug it in and follow the prompts on the screen. Its not hard.

[Never had any say Panda]

Are you flattening the accelerator pedal or just gradually increasing the amount of pressure your foot applies.. ? Usually they only hit full boost at WOT..

Foot to the floor n on goes up to 8 psi

You aren't providing enough info. No one on here will be able to tell you exactly what is wrong no matter how many times you repeat it and even then we would be only guessing.

There have been a couple of suggestions made but if you aren't comfortable to diagnose them or even use the flash tuner then you need to find someone that is.

How about giving your tuner a call?
