He may have, not sure. But I don't think ignition is the problem.

 

Sounds like your EGR vac line is off. That will do exactly what you are describing when trying to put air into the system. It is under the throttle body on the end of the intake manifold. There are two hoses. The hose that likes to pop off is on the back with the nipple pointing towards the passenger side. It's hard to see but follow the hoses with your hand and you will find it

Thanks Bryan! I will check it when I do a compression test.

 

Just heard back from him.

"E85 duty cycles were a peak of 78%. Pump gas looks to be around 46%.

11.2:1 AFR’s on pump with 27 psi of boost, holds the boost decent. 11.9:1 AFR’s on E85 with 34 psi of peak boost, also holds boost decent."

 

I think its Tim to check your compression an do a leak down test.male sure you check the egr hose I it popped off an i would gap your plugs to 20or 19..

 

Will do. I don't see why he would've put them on my car without gapping them..?

 

it sounds to me like you guys are all pointing fingers at a tuner when the ops car didnt perform. when you make an appointment for a TUNE that is what the car is there for. not to be FIXED. you shouldnt be taking a car to be tuned that hasnt been looked over 100% beforehand.

to the op. there could be many things holding you up. what were your iat's by the time the e85 pulls were being done?(crap ic) you werent running arp's?(head lifting) where did you get your e85? im sure your walbro isnt maxed. i made identical power at identical boost on e85 and the injectors were still trimmed all the way down to 6xx something. dont remember off hand.

ps : sell those injectors and buy a new set. the 1450's are horrible for any tuner to work with.

 

I had a customer come in with a similar issue. The car was tuned but it wasn't making the power it should. Immediately after the first pull, I noticed the boost came in later than a typical FP red 2.0 evo. I started dianosing the boost controller and wastegate. Then found the wastegate being help slightly open. I then took it off to try and tighten it more so it would stay shut. Turns out it was already tight all the way. I had another 25 psi actuator on my FP black and tried that. While I was bolting in on, I noticed right away that it was gonna stay open. Seemed like a fault with how the actuator bolted up. The solution I came up with was to cut the threaded part of the actuator rod so it can have shortened.
Ended up with almost 100 more whp and had to back the boost down to have around 440whp where the single pump maxed out.

Take the lock pin off of the actuator arm and see if it comes off easily or if the arm sits close. There should be some tension to pull the rod off of the arm.

 

Not sure of IAT's, but at the end of the last pull he said one of the reasons he was done was because of overheating. I have the 84mm inlet for the red, although I had to use my old intake pipe (2.5" inlet to 3-3.5?..whatever the MAF size is..) because FP didn't have the bigger pipe for the red. I may still order FP's bigger intake pipe for less restriction.

I was not running ARPs, but I did buy some while I was there.

e85 was bought from Meijer in Mishawaka, IN. I also have a few other places I can get it from. (McClures and some other stations)

Yeah, I didn't think my pump was maxed and David confirmed it wasn't.

Do you see this on a lot of FP Reds? And if I'm reading this correctly, you're saying to remove the pin at the end of the rod and see if it is easy to pull the rod of the arm by hand?


Thanks for the replies guys.

 

Theres only a handful of Evos out here in our small state with the Red. This is the only one I've seen with this issue.
Yes take the lock pin off, slide the rod off of the arm. It should require you to pull the rod towards the arm to put it back on. If the rod goes back on without pulling on it, then you need to adjust it.

 

Thanks for the info! I will have to try this. By the way where are you located?

 

Minnesota sir.

 

Wait...is the intake tube smaller than the MAF? Maybe that's your restriction? 3" wouldn't be a restriction but 2.5" might be.

 

A very valad point lol... comment withdrawn. Any updates?

 

Intake pipe is 2.5" on inlet side and increases to the diameter of the MAF.

Haha, no updates yet unfortunately been busy with work. Hopefully tomorrow though.
