mayeb you have a leak, or a craptastic bpv, can you be more specific about what happens.

 

[fastsaab1]

when in 3rd gear it will pull great then it will loss boost slowly down to 10 psi blow off valve is good all clamps are tight just losses boost

 

[Marks900SE]

Do you have the stock BPV? If so they can only withstand 15psi maybe once :roll:.

 

[jrbrangi]

yea if you need to upgrade the BPV go with the Forge or Statmosphere Hyperboost

i have a turbo xs rfl or what ever the one with the big horn on it

 

[stromer]

Yes, that's the turboxs type rfl is the one with the big horn. Mine hold 15 psi just fine, so its not that. What do you have for a boost controller? Some get dirty and will surge for a bit, then boost will settle. Mine did this, but after I cleaned it, boost was much more consistent.

 

[jrbrangi]

how'd you go about cleaning it? just curious for future maintence. Compressed air?

 

[stromer]

Exactly, I just took it apart and blew the crap out of it. Mine is the truboxs mbc (I think there are other specs with it, but not sure right now.) The top came off and that's all I had to do to dissasemble it.
