2G Big problem, cut at WOT

[Heryst78]

Hi guys

I come to you because I have a big problem with my GST eclipse of 1997.

the problem is that when I acclimatize, arrived at 4000 rpm, the turbo cut, and I feel that my engine exploded.

I read on the forum that there was the phenomenon of "fuel cut" which could produce this sensation, as if I entered a wall.

however, the engine of the eclipse is original. I have only one system of exchanger, and a boost controller closed thoroughly.
I have 1 bar to my boost gauge, and the AFR is perfect (14.7 in slow motion, 10 accelerating at bottom so not poor at all)

Has someone already had this problem ? it only happened to me once but it worries me.

injectors, gasoline filter, air filter, everything is new.
the only problem I have on the car is my throttle position sensor that sometimes goes into default. I cut the engine and then I restart and the CEL is gone.

thank you

Fill out a profile page. Fuel cut isnt based on fuel ratio etc. Its airflow. I understand English doesn't seem to be your native language. We need to know mods you have.

I updated my profile
I put a picture of my car

yes, i am from paris in France, I use Google Translate to write to you

I presume that by Mods you mean the engine parts I have no?
On the eclipse I have:
- An ebay intercooler with all tubes and hoses
- Turbo t25 of origin
- A manual boost controller
- Injen admission with a K & N air filter
- A dump Valve Forge
- A black turbo eprom
- Exhaust line after HKS catalyst
- An AFR gauge
- A turbo pressure gauge

for the original OEM parts, I replaced the throttle body, all the intake and turbo gaskets, the injectors are new.
I did a boost leak and no leak
the EGR is doomed.

and that's all

the EGR is doomed.

The best thing I've seen all day!

Why it’s bad ? On our cars in france we always doom it

I think « by pass » is a better word
