Fuel and boost question

[Tuna_no_crust]

hey I have a couple of questions n I would appreciated anybody's input.
1) my car has 560 injectors in ( bought the car like that) would the car idle fine if is not tune with those injectors
2) when I do a 3 gear pull and I hit about 11-12 psi my car makes a loud backfire something like fuel cut
3) I have really bad gas mileage and as I go wot a/f goes down to 10 ( the most my wideband reads

Only mods on the car are 3' full exhaust and a 16g with the 560cc injectors

 

[GST with PSI]

For starters, your 3 item mod list should include a tuning solution (among many other things).

Your injectors are over 100cc's larger than stock, yet you have no way to compensate for the extra fuel being delivered. Does that give you any hints as to why your fuel mileage probably sucks ass?

This ain't a small block Chevy tuna buddy, any modification needs compensation. You have to tune the car for these changes or go back to stock setup. I'll put money that a bone stock DSM would run circles around you right now.

"well my friend im running a 16g with all the bolt on, on stock fuel an im hitting fuel cut at about 16-17 psi. by the way I have a fuel system to support way more than a 16 but im just too lazy to put it on right now haha"

Then theres this thread:

"What happens if my actuator has no vacuum line connected to it?"

Where you said:
"And I have a 98 gst 3' straight pipe, front mount inter cooler, 16g, 1000cc deathwerks, 450 walbro ( got a good deal on it ), aeromotive fpr with upgrade braded lines, fuel lab filter with upgrade lines also, aem wideband and boost gauge"


People have been trying to help you for months. Please just sell the car. It will be the best for both you and the car.

Well yes people been trying to help me with my car for months.
2- all of them question I've ask are for when I put on the parts I bought to tune the car
3- if you don't like when I ask a question don't come to comment with your negative comments trying to be funny

Put stock injectors on. They can be had cheep on classified here.

14b can also be had for Pritty cheep, Stock waste gate pressure 8psi until you get a way to tune. Or stay out of boost with your 16g, with 450cc stock injectors.

Once you can tune, put 560 back in with your 16g at 18psi but GET A TUNE. No way around it.

Bad fuel consumption as stated before you have 100cc bigger injectors but no compensation. That is your problem. If their is a problem fix it, don't do more pulls thinking it will go away.

No one is trying to be funny, just conflicting info as iv read your posts. Get those 550 out and start fresh and stock with maintenance. Then build up, it doesn't seem your ready to add parts yet as I'm not sure you are aware of what they do. Google search your question and put DSM after, I get all my info like this and have no problems. Just may not be the first thread where you find your answer. Not trying to be dickish just trying to help.

I have a way on tunning it I'm just waiting on my flash cable so I can do some logging. I just wanted to get somebody else's opinion to see if my conclusion was right

 

[2gGst98]

Well good luck and hopefully you can get that thing tuned and get some power out of it. I take it all the maintenance is up to date.

If your using evo scan for loggin, a 1.3 cable logs at a faster rate, then use the 2.0 to flash. I use the 1.3 cable as it was cheaper and I read it is a better cable to use for logging just my .02$

 

[Tuna_no_crust]

Thank for the advice about the cable. And the car is up to date, new timing including water pump, plugs, wires and coil pack all new. All fluids have been change new valve cover gasket the only thing left is cleaning up the engine bay since the car had a major leak before I got it.

 

[2gGst98]

Sounds good. And a vagcom 409.1 can be had for cheep, I have an extra if you need. I'm sure I can get shipping cheep if you interested. No charge if shipping is less then 10 bucks. PM me I can have it sent tomorrow. You may have to fine the files for it on interweb but many people here have it I'm sure. I just don't have the CD anymore.

I plan on switching to Link in about 2 months so I won't need my extra one anymore, as it won't work with link.

And just read you name hahaha I likey

 

[2gGst98]

Actually if you are using evo scan 2.6 or lower it will work, just read evo scan 2.7 has blockers for this cable so it may not work with your set up depending on the version you have.

 

[dsm fanatic]

well if it is tuned right it would not have problems idling and for the second question it is not getting enough fuel, but the third question idk about.
