Went to the track with a GT3076R. Not Happy.

But your response can't be helped, after all your Mr. Boost leak's left nut. You swing every direction he does.

The tune for the stock turbo won't work, Fuel and timing control will be off especially once you change manifolds. Your entire power line has changed don't expect it to do well, I mentioned this before. You can't slap on a turbo, not tune it and exepct it to do well. You would probably run better with a nonflashed ecu honestly. (no pun entended just becuase the custom tune is custom to the stock manifold and turbo)
I run the GT3076 and trapped 106-108 at only 19-20psi with a 3-3.5 sec 60 foot time on 91 **** fuel and still ran high 13's very low 14's. This was even with a turbine hotside problem that is now fixed. It has potentional once you get it tuned and lined out, good luck.

Guys, the tune difference is not that bad between the 30r and stock turbo, I know, I just did it last year! I had a dynoflash tuned for a stock turbo and went to a 30r with no other changes, yes the tune was off but not that bad. He has a SAFC and should able to get pretty close with it. He just needs to watch how much fuel he pulls out for the alky to be sure the timing doesnt go through the roof.
If his afrs are where he says they are then there is something else wrong with the car. Go back to simple diagnostics...boost leaks, compression, fuel, bov leaking, plugs...start at the maf and work your way back. Make sure the turbo is on tight, check your wg to see what pressure it cracks open, same with the bov. Do a pressure test. Be thorough and do it right. Spend a Saturday checking everything before you try and tune again.

In my case using the tublar manifold the detonation zone 5000-5600 peak torque zones was much more noticeable.

I have to ask...how do you run a 3.5 60' time

At this time I was shooting for a 11.0 afr on 91 pump and I ended up pulling like 3 deg of timing in the det zones but I was able to ramp up high in the upper rpm range. It was a give and take situation.
Issues are all sorted now and this year will be much different don't worry.

My 2.3 60' was because it was my first time at the track with the Dynoflash 2 step and the tires grabbed the track too much. On the street, I cant get the car to hook up through 1st gear and starts going sideways. I'm still looking for time to look for a boost leak, I just busy all the time. FYI, I have never been to the track with the car tuned. Last night I did some more messing with AFRs. I kept pulling fuel out until it was flat with the Dynoflash and it was still at 10.8 so I just left it but haven't drove it hard tell a difference. I'm going to pull more out if everything goes ok. I'm guessing that will help the injectors out a bit. I just dont get it because the turbo hits boost more violently that the stock turbo. And I cant shift fast without grinding and/or missing the gear. The only time I nailed a flatshift in the Evo was my first time to do it from 3rd to 4th with no grind, went smoothly. After that, it was the same tranny that was notchy and would allow fast shifting. I still use Synchromesh.

I started out by adding 7-8% of fuel over the Dynoflash, now it is at 0%. The Alky comes on at 16-17psi. BTW, I normally use water on the street and a mix at the track. I am reading the AFR's off a LM-1, no AuxBox to log air/fuel. Could the advanced timing in the wrong rpm range make the car that slow? My main concern is getting my trap speed up about 15-20mph where it should be. 101mph is not good for 24psi.

This is the example of HOW NOT to mod your car. If you are never getting close to where you should be in terms of trap speeds, then you shouldn't just keep adding mods to hopefully gain more power. This car definitely has something wrong, and it's a terrible idea to run on a big turbo with a non-progressive alky kit without being tuned for it. That's very dangerous and completely useless, imo...

Watch what you do here...don't make a 3rd gear run with no alky right now. I would make sure your can log afrs/rpm before you go to far from here. I still think you have a problem in the 3500-5500 rpm range you cantt see without logging. I would try bumping up the alky hit to around 19 psi and run at least a 50/50 mix. Why not run 100 alky?
I think if you log it right now you will see a big dip when the alky hits and you would also see afrs slow to recover after a shift.
