I was reading through the forum and found the stock 03 evos should be hitting 19 psi at 3500 rpm and taper to 16 psi by 6500 rpm, i've never hit 19 psi at all since I got the car (bone stock, unmodified with 45k) i max at ~15psi

since the mods i've added and still untuned still had same spool characteristics, last week i added short uicp and a licp and got a tad bit faster spool but still not getting up to 19 psi. I searched and found it could be the stock bcs and removed the line to the wastegate and boosted to infinity in 3rd gear (stopped at about 20 psi)

so is my bcs bad or wastegate, or did i read wrong.

 

Is the pill still in the line? I had a car that it was missing and had similar symptoms as you

 

yea last time i check they were both there because i accidentally took out one of the lines with the pill and was hitting 10 psi max but put it back, but i will look again when it cools off. are both pills the same size?

 

why havent you had the car tuned?

 

had a kid so funds were on hold and needed to finish getting the rest of the parts but im getting tuned around in a month or 2

 

You should do a boost leak check.
I think the tune will fix allot of your issues. There are a few good e tune guys on the forums if you are looking for a cheaper route. That would be my next step in the process after the boost leak test.

 

did many boost leaks replaced TB shaft seals and no leaks after that.

found the both pills

 

Install a MBC and also increase WG spring pressure up to 17 PSI.

 

yea that was going to be my next step, if I cant find a decent one on here im most likely going to run an ebay voodoo one for the next month because i will be getting tuned for ecu controlled boost.

 

Mine does similar thing after car went back to stock. Max boost 16 and tapers 14. I had big boost leak from TB seal and Fuel injectors but after fix, still does same thing. I am thinking borrow boost gauge from friend. Mine could be off. What should do next if that doesnt help? Check exhaust leak? Let me know how it goes.

 

+1 on both. Get ahold of Tom at VRSF (tcompusa on the forum) he offers great customer service and a REALLY affordable rate. Just gotta have some thick skin if you're trying to learn during the process
