i'm not sure if this is the right place for this question but i need some help. first let me give some info on the mods done to my 03 Evo. HK$ rs intake, greddy type-s bov, hk$ dp and cat-back, Works Rally p2 ecu flash. oh i also have an AMS fmic.
the car seems to bog a bit before 19 psi and then spikes higher than 19 and comes back down. it does not do this all the time. i beat on it a little it seems to get better. this happens even 30 min after after driving so it's not a cold condition. i've tried putting the stock bov back on and it still does this.
I'm a tech at a honda dealer but i don't know alot about driveability concerns when it comes to a turbo powered stuff. please give me any insight!.
oh and i also experience lack of boost in 2nd gear. when this happens it will not go past 1 bar. if i let off the throttle and punch it again it will be fine. is this a waste gate problem?
Please help thank you.

Check to see if your BOV is defective and then see if any of you intercooler hoses haven't popped off or are loose in anyway.

 

thanks i'll check that.
Has anyone heard of any wastegate problems???? Or does anyone else have any other ideas??
thanks
