im running the 58./57 precision and my boost will reach max then drop (sounding like my wastegate is opening early i dunno) then builds back up and my ******* maf (p0101) coming on a lot lately i just keep clearing the code, i have no boost leaks, (have not done a smoke test, when i do a boost test i dont hear air anywhere coming out ..oh yea internal wastegate fyi

 

where is your MAF located. Pre turbo or post turbo?

 

pre turbo - same place it was on the intake as it came stock

 

Check your evap purge valve. It might be leaking.

 

Vacume line going to your wastegate may have a leak. What wastegate is it? When you do a boost leak test you need to get some soapy water and spray it on all your couplers and look for bubbles.

 

internal wastegate that came mounted on my new turbo--- 12lb spring and did the coupler spray as well alrdy when boost testing no bubble anywhere.. and i checked my line to the wastegate its all good

 

boost controller?

 

How much boost are you making max? Who tuned it?

 

25psi hptuner ..kevin from burlington and im spiking 30lbs..

 

If its not a waste gate issue then its in the tune. Are you using the factory boost solenoid?

 

yes i still am

 

yes still using the stock solenoid
