NEW motor. Seems to be running lean, Help?

Hey, it's me again!! Again, I just got done putting my motor in and my check engine light came on. So I went to go see what was going on. I plugged in and it says it running lean. Before I took my motor out i got it tuned with 565cc injectors. I took the motor out and put in 750cc injectors. I have a tune scheluled next friday. I cleared the code this morning and It has not come back on yet. So I'm just wondering am I going to be ok?? Or what can I do?? I am changing the oil tomorrow and since I've been breaking in the motor I have not gone into boost... So should I go to a shop and adjust or am I fine or stop driving it!?! I only have about a 100 miles on the motor so far. Again it's a 02 wrx with a built block. HELP!!!

 

so you're running the old tune with the new injectors?

 

Uh, lets think about this, there is a 25% difference in injector size.

No, you're not going to be "just ok." Get a basemap for those injectors from your tuner before driving any more.

 

your fuel trims are jacked, lol

 

ah, sadly,yes...

 

dumb on my part I sure, I know you can say it.

 

dont drive it until you get a base map to get it to your tuner
you should ask your tuner for a base map

 

Why don't you have a wideband? They're not that expensive. Shuns on anyone who mods their turbo car without one...

 

Dumb of me I know.. I planned on it!!

 

I need to go from Kato to Burnsville. I need to see if someone can help me out around here.

 

Done and done..:hsdance: going for a tune at the end of the week!!:run:

 

Problem is it's a Subaru.

 

Thanks for the tip.:cheers:
