i have the same turbo running e85 with a Junior speed density tune on an AP. I also have big lines and rails, aem 3 bar map and an Aero 340 hardwired. Had similar issues at first, ended up being 2 bad Aero 340s. Third one did the trick.

Also, arent those injectors a little big for the stock ecu? I thought the ID2000's required stand alone fuel management like hydra or aem?

I would try the double pumper, as you pretty much have everything you need to do it.

I went straight to blow-threw and speed density on mine and never had any idling issues, I just started to blow the MAF electronics off the tube. Fixed that, and haven't had any issues since.

If you have a Cobb tuning facility near you, get the accessport and have them do the speed density protune. It's a little more spendy, but after 4-5 months of trying to figure out this problem, it may be worth investing in. I got a speed density protune and couldn't be happier with the results. Perfect drivability and great power!

Yeah I am still struggling with the car, more or less to the point I have given up on it and the car can just sit. I go back to Nebraska a few times a month and don't even look at the car anymore.

After re-reading this again, I'm first of all curious about how the bigger intake helped / didn't help.

Secondly. . . You are trying to run 500whp on stock lines on E85. That is a lot of fuel for those lines, which I think might be part of the problem, not the entire problem, but some. There is 44% more cross sectional area by merely jumping from 5/16" to 3/8" (6AN). It would be relatively inexpensive to test some push-lok fittings and rubber hose to see if it helps, and if it does, just upgrade to stainless lines. FWIW, on my ~500whp E85 build I'm doing a walbro 255 feeding a surge, 2 044s feeding -6 lines, merging to a -8 line to the rails. From what I've heard, 500whp is the limit on on 93 you need to take 30-40% off that for E85.

Just my .02 again.

The issues that have frustrated me to the point of giving up on the car is the terrible idling, misfires, etc. All occur at idle or just cruising around. Car was taken apart in March expecting a fun summer with track trips praying not to blow it up...instead it hasn't left the garage unless for a short drive to do some logging. My friend who had the car for awhile took the car to his house and had his "tuner" mess with it. Said he wouldn't charge unless the car ran better, given that he has been tuning my friends EVO for quite a few years and seems to be pretty good buddies with him I said sure why not. Well car ran like total ****, guy didn't know what the hell he was doing with a Subaru and disabled all kinds of things and didn't bother scaling the MAF, after I told him I wanted to just call it quits and part ways it turns out my buddy had already fronted the money for a "tune". The tuner MELLON RACING (total **** btw) wouldn't refund my friend who is a loyal customer of his so I just paid my friend since it wasn't his fault the guy is a douche.

I started the car on May 13th after getting the new turbo kit on, car ran and drove sort of. I have spent about $3000 just trying to get it to run right. Frankly I am just tired of spending money on a bottomless pit. I probably could have just dropped the car off at a shop and picked it up for less money.

On a positive note I finally just went to the bank and paid off the balance of the loan b/c I am tired of paying for a car I never drive.

Does the car currently have a solid tune on it? You gotta figure this out. Do you think there is a short in the wire harness? My guess is some type of wiring problem in the coilpack area.

Maybe switch up those fuel rails, PIA but might be it also.

Car as it sits has a very basic tune on it with the new KSTech intake. After getting taken for cash on that screwy deal from my friends tuner I am not sure what to do with the car right now. I have spent a lot of money chasing false leads with not a whole lot of luck...

The car ran fine on the old stock turbo set up so I don't think the harness has an issue, has to do with the new parts/setup on the car now.

CJ, I think Jason was fairly confident we can work with it now. At least we had talked about it on the drive home that night.

Talk to one of the real tuners who have posted here. I know you're aren't there much, but Junior isn't that far from you. I'm not sure who else is around you. AMS doesn't tune non AMS builds anymore so thats out...
is someone in Indy any good at tuning?

Get an accessport and speed density protune. The MAF is a PITA with a turbo that big. Once I got mine all the problems you are talking about went away. My walbro 255 was maxed out at 400whp on 92 pump.
