Reinstalled my GT2871R and ran into a problem. I was giving it some gas and I lost all pressure and it went into limp mode. I tried restarting it, but it would immediately die. I got the standard misfire codes for all 4 cylinders and I got this one-

P1556 Charge Pressure Contr. Negative Deviation

Any help would be greatly appreciated.

The silicone hose that's connected directly to the turbo got blown off. All better.

 

Hey! You wanted more power, don't u ?

Did you get elim or normal gt2871r ?

 

I was gonna say LEAK but you already knew that. I just got done doing a FMIC for a friend on his 01 jetta. He thought he would be cool and pull the hose coming off the turbo out pipe that goes to the DV to make a BOV kinda thing. Laughed and told him that it might not even run, HAHAHAHAHA, two min. latter and a bunch of realy black sutty exaust latter. He agreed with me. glad to hear you got it workng right.

 

Arif- It's the eliminator I had on there a while ago.

I still have a boost leak. I'm going to change all the vacuum hoses out tomorrow. Some are rotting.

 

If you remember I had a leak too when I first run my car. Prob. your plugs do not fire anymore b/c rich runing for a while (all blacked out and wet) that's why it is dying so fast. You should get new plugs too.

 

I just replaced the plugs on Thursday. It runs like a champ, just not enough boost.

 

It runs sweet now. The unitronic tuning is so much smoother, even at idle the car sounds completely different than it did with the GT2X in it
