Problem around 18lbs.

[BAMBAM]

As you all know I am on ALky and, I am having problems at around 18lbs. I installed the FMIC and I had no problems until I did that. Could this be a boost leak? I start building bost and then it feels like I hit a brick wall at 18lbs. and it sputters until it hits full boost then tapers back down to like 19lbs. Never had a problem until I installed this FMIC. Is someone around me able to help me do a boost leak test?

Why don't you do a quick visual inspection of your IC piping and see if there's anything loose. I'm sure Lucas could do a leak test for you for next to nothing if you asked him nicely. Good luck on this, I know how frustrating it can be when somethings not right.

All ready did that. and I am starting to think that the front mount could have a problem? It feels like it is choking. It could be that since I cahnged it, I may need another tune. Justin said I don't though. this is really wierd. The really wierd part is that it dd fine no problems until I hit a high boost around 18lbs.

If it "feels like hitting a brick wall," it might be fuel cut. With the addition of a FMIC, better effeciency, turbo works better, more air comes in... blam o.
What's you boost limit raised to?
Are you able to log?

I am guessing you are using a MBC? Also, if you are, then you may want to change your settings to 319 to avoid hitting boost cut/fuel cut. Let me know if you need help with setting this...

What gear are you experiencing the "hit a wall"?

[BAMBAM]

Justin did my tune. So I have know idea on that. And yes this is a MBC st at 24lbs. but it is not getting that high though on the gage it only hits it foa sec and drops to 20lbs.

check your plugs, it happened to me on my evo and my 2g eclipse.

[DynoDude]

What spark plugs are you running?

[BAMBAM]

Hey Lucas I am running bbr8es. With my alky and tobz told me that I can run those.

[DynoDude]

Well with your new Intercooler you are going to be running colder charge temps (especially with this cold weather) with cold spark plugs (BPR8ES I assume) so you are blowing out the spark possibly. Try using some BPR7ES which is a range warmer and it should cure the problem.

Let me know if that works

[JustDSM]

It's not hitting fuel cut, I'm sure of it

[BAMBAM]

Hey Lucas it did help out. But I think you are right I need the coil on plugs it is still doing it when I hit the gas fast. It was fine friday but sat. when I started up the car, and warmed it up. I Thought why not hit that 24lbs so I hit it and it is poping again and only hitting 20lbs. Now if I go slow on building boost I can hit the 24lbs again and it pulls hard.

[tobz]

Yea, Scott the 7s are most likely better in the cool weather, when I started to think about it. I wonder if the warmer 6 plug would work even better.

[BAMBAM]

Hey tobz Did you have that problem at high boost with the ALky kit blowing out the spark? I think that is what is happening.

Maybe you need to bleed your brakes, that may fix this problem.
