I just had my engine rebuilt and streetported. I have a couple of questions maybe you could help me out with.

1. What should i adjust on the engine (it was mildly streetported) there should be some thing that need to be adjusted aren't there?

2. I have an 88 gxl is that a 4 port or 6 port engine?

3. I am having problems with the idle, when i am driving normally it studers at 3500 rpms (can't figure it out)?

Thanks in advance for all the help.

 

1) larger injectors or an s-afc since its going to want more fuel

2) 6port since its NA

3) thats te notorius 3800 rpm stutter. ground the ecu better do a search for the writeup.

 

thanks for the suggestions ill try them

 

My opinion here:
If it's a mild street port, your injectors are fine.

 

Cwaters is correct. Factory N/A injectors are good for 220 HP at 80% duty cycle. You don't need bigger injectors, but something to control them would be nice. A stand alone EMS would do wonders if its properly tuned. Remember, more fuel doesn't mean more HP. You need more air. Get a stand alone and get rid of the AFM. That will be your biggest improvement.
