Alright my car makes 650whp on the dyno (perfect). On the street it runs like dog crap.

I have a 255 feeding an 044. I am not logging Fuel pressure yet. Could I be draining my basket? or is the 255 simply not keeping up with the 044. Stock lines the 044 is in the engine bay.
I am using ID1000's

My base fuel pressure is 75PSI. Anyone see this before?

 

do you have a wideband in the car? is the boost acting right on the street?

 

No Wideband. yes it hits 30psi on the street no issues

 

 

that mess looks laggy as hell.

get a wideband in it.. regardless though with 30psi it should move out alot quicker than that

also, your ignition timing looks all jacked up.. its flat, that is not correct.

 

agreed

 

who drives a 650hp highly modified car around without a wideband lol

ignition curve... well line i mean looks really bad

 

Honestly this was my first question when I read that.

 

My first reaction to this thread.

sad face is sad.

 

Since i was having problems I just set it to 18Deg in boost. Just to kinda rule out the the timing thing.

I never ran my civic with a wideband, I got one i am going to toss it in.

My question wasent really tuning related, just if anyone had issues with the 255 feeding the 044.

 

If you had a wideband you would see it go lean if the pressure was falling off.

From what I've seen, plenty of people have done that, however I've seen most of them run the 255 into a small surge tank, and then feed the the 044 from the tank.

 

The wideband and pressure gauge to AEM are getting installed tonight.

I will get to the bottom of this!

 

Sounds like a shotty tune to me...

 

Where did you get the car tuned?

 

sounds like a 1hr tune..

 

I tuned it, It was the main relay was all hacked up....

I will be at IFO on sunday
