Dyno today.......unhappy
Hell I put down 344/342 on stock turbo at 21psi. 5,000 feet elevation, 80 degrees, 91 octane. Something is definitely wrong.

You "trust" Dave Buschur when he is saying that he may have given you the wrong turbo by accident OR that you have a "technical issue." Yet when I was standing right next to you at the dyno day this Saturday and Big Al said the same thing, that "there must be something wrong with this turbo" or "you may have a boost leak that needs fixing" you declined to spend any money to have a tech do some tests on the car and try and determine what the issue was. Its obvious that something is seriously wrong with your set up as stock turbo cars make that power on less boost and if I recall your car made that much power on the stock turbo also with your dyno flash. If you were rational and sane you would have gotten the car looked over while it was here at the dyno day, spent $45 for a half hour shop time and your problem could have been diagnosed and resolved. Instead, you choose to leave and post insults on the internet about the guy trying to tune your car, who did not sell you any of the parts and who did not install them. Funny how now you are seeing the light that your situation may have something to do with a defective turbo or boost leak. You could have been racing this Saturday if you had just listened to to the advice you were given last Saturday.

Take a 5 minute trip to a home depot. But a 2.5" pvc plastic cap, and 5" length of the same diameter pvc strait pipe. Get some PVC glue while your there as well as a tire valve (will be in automotive section)
glue cap to the strait section. Drill hole in end of the cap that is smaller than the tire valve. pull the tire valve through...BAM leak tester. you will proboblyneed a 2.75 to 3" silicone reducer to meet up with your 3" turbo inlet.
hook that up to an air compressor with a regulator and set the input pressure to ~20psi.
Squirt soapy water around your Ic pipe connections and especially around the rear of the intake manifold. my evo had a lot of boost leaks behind the intake manifold.
HUGE HUGE differance boost leaks make. especailly in a car with mass air meter, as all that air volume going through the maf causes the car to run richer and with less ignition timing than it should.
Take the initiative and fix your own problems....the time you spend on this forum *****ing could be spent making your thousands of dollars of modifications work.
I have been to Dan's shop 4-5 years ago, he's no crook. you would be wise to seek his help in diagnosing what's up with the car. Stop throwing $ into tuning and additional parts untill you get it running the way it should.

Re-opened after cleaning.
Keeping this around because there's a tiny bit of useful information in here.
Anything else out of line by the principle parties and the thread goes in the trash, sorry guys.

I saw that Dan's shop was in the northeast, I guess that post was deleted for what ever reason. But my question is where in the northeast? I am most likely getting the rrm turbo for my lancer es in feb. or march. The only shop I found by me is speedworkz. I noticed a lot of people from the west on this board. If anybody out in the east, PA northern part to be exact, can help a guy out it would be appreciated.
Buschurs car had an ems, ported head and on a two wheel drive dyno, thats were the 504whp came from at 25psi.. So a car without an ems, ported head and on 4 wheel drive dyno is looking at a lot less hp..
I agree that the reflash is a bad idea at that level. Sure it's easier, but it just doesn't add up to me.
I've said it before, and I'll say it again... tuning tuning tuning.

How could it be the tuning if other people HAVE made the power on that same dyno with the same tuning (reflash)? Rollaway made 444 whp with the AMS turbo kit, and I made almost the same power just yesterday at Pruven on the stock turbo! https://www.evolutionm.net/forums/sh...ad.php?t=97917
Al has also made over 500 whp with a reflash on his car. Regardless of tuning, the results Kevin got with his setup means something is mechanically wrong. Even on a completely stock ecu, 28 psi on a big turbo should be more than 380 whp.
