crazy boost on 04 srt4

[srt927]

dont have part # on hand just got it today though the revision is v9r17 for and 04 srt-4 neon installed the 93 tune today went out for some pulls and it started off fine but as soon as i get around 4k rpm boost spikes to 25psi then at 5k it hits fuel cut... im still stock other than 3" exhaust aem intake and a short throw shifter what could make it run so bad

Do you still have all the stock vacuum lines hooked up?

I've never really checked got the car a little over a year ago now it normally boosts between 14-16 and i know its the stock wastegate i was really hopein to just plug and go with maybe minor modifications to the tune but this seems like its somethin major
