Newbie with new problems
Hey everybody, new to this forum. Been reading lots and need help. I have 2015 lancer that is boosted. Its been running great until we turned up the boost. He wanted to see me at 10psi... But this is a little alarming do to the fact I have a MBC set for 10psi. I also have a turbo smart wastegate set up for 10psi as well. So in theory I should be at 10psi right from the start. Since this I have ran into issue after issue. I believe I have a big boost leak. But cant find it. Ive checked everything twice. No luck. My car just as of a week ago started to bog down with no acceleration. Holding -19 psi of vacuum at idle. Then says 0 when driving around 3k rpm. When I try to go it sound okay till about 3500 rpm then my car makes a weird loud drone sound. Like not enough air going through a big pipe or something. Idels fine just no acceleration at all. Takes me 45 seconds to get to 20 mph.
I've replaced my maf two days ago no change.
I need to do a boost leak test but dont have access to a compressor.
Turbo is a 16g td05 off a evo x
Custom hardpiping for lower and upper ic
Modified downpipe to fit stock exhuast with greddy axle back.
If anyone could be of help that would be great!
