BOOST LEAK.
Put your stock intercooler back on and let us know the reults. This will cost you $0.
Take the intercooler to a local radiator shop and have them pressure test it ($30) or go to home depot and buy a cap for one side of the cooler and make a pressure tester for the otherside yourself (priceless).
As i mentioned before, there is a BUG in your set-up somewhere. You may be lucky enough to have found it in one shot.
Atp is not as good as Buschur or Ams-- We all know this. Facts are you own one and it's on your car now. Please don't be so quick to blow money away untill you work out all of the weaknesses.

im going to switch the intercoolers today and do another boost leak test. the turbo is putting out 28-29psi and the motors only getting 24 so something is up, but i dont think changing an intercooler will make me 50whp

You'll get more than 50hp from the motor getting another 5psi from a 35r at those boost levels. Do a search.
What you have done is found just 1 of the 'bugs' in the car at this point. Go over it with a fine toothed comb.

Just because you can buy a part doesn't mean you know anything about it. If you did you would have never bought the kit. I drove an atp 35r car around for a year. It belonged to my old roomate. Slowest car I have ever driven. You have barely any power under the curve. An ATP 35r kit spools around 5200-5400. You will have trouble breaking 400whp on pump with it. Then get laughed at when stock turbo cars walk you all day. Also no matter what manifold you put on that it wont do anything.

For all you ATP bashing people... what makes your garrett turbo better than ATPs? (proprietary parts excluded)?
Original poster... who's tuning?

Also the problem is not the intercooler. Those work fine and this problem happened when the kit was installed. How do you know you are boosting 29 but the motor is only getting 24? What gauge are you using? What boost controller. Some gauges are way off.

dan over at pruven is tuning. im not bashing ATP, my buddy has a ATP 35r kit and hes made 420whp without cams or intercooler piping, and with out meth at 23psi. i thought i would make more than him since i have cams, intercooler piping, and meth. both cars were tuned by the same tuner. i made this thread to get some info on what can be wrong with the car or turbo on why its not making the power.

i have two brand new autometer guages hooked up to the car. first i hook both of them up to the BOV line, got a reading of 24psi on both the gauges, then i hooked both of them up to the nipple fitting of the licp, and got 29 psi on both of them. last i hooked one up to the BOV line and the other to the licp. the bov line i got 24 and the licp i got 29. i also did this test with a hallman boost controller, forged, and a buschur inline, im getting the same reading.

They is not garrett. Garrett did not have a twin scroll design when the ATP product was made. Now days if you so choose to have a ts hot side, all you have to do is ask.
The lack of TS is not why he's not making power.

sorry to hear that, i would sell it. That turbo comes alive when you rev up to 9k.
I put together 35R myself because my friend was selling it cheap brand new with tial WG.
True greedy 35R BB with .63 hs, for better spool, full race mani, Tial wg/dump tube, custom oil/water lines/ intake/downpipe/buschur slimfan, the car runs good! on pump 21psi but i cant prove it, until I tune that bisz on race gas and throw it on the dyno and see what it shows
Im doing this for fun.
I love 35R's,one thing that is left is build 2.0 or 2.3 stroker kit+AEM.
