660cc to 880cc

[gsx219]

ok im getting some 880cc injectors and getting rid of my 660's and was wondering if i would need to get it retuned right away or could i go for like a week or two before hand..

If it were mine I would get it retuned right away because if not you will be running really rich. The car will more than likely idle poorly and drivability will also suffer.

I agree. If you have it set to run 660's and then drop in 880's, it's going to want to push the same amount of fuel through the bigger injectors which will cause you to run rich. I would get the system adjusted for the 880's as soon as I could.

thanks for the imput guys wasn't to sure on that one cause im going to get my car retuned and dynoed and ill install them there or before i go.

judging by your profile, you're using an afc for the 880's?...that's not going to cut it buddy. why sacrifice tuning ability when you have a 3052. those injectors are too small for the 3052 anways.
my friend has 950cc and on race gas, he's at 93% IDC. i'd go 1000 or 1200cc if i were you and a dsmlink or aem.

well just the afc for the 660's right now and the afc is doing fine. didn't know i would have to change my piggy back system, i was wanting to go with the dsmlink but i have to find a eprom ecu. so i guess before i do anything i need to get the dsmlink???

1512gvr4 is correct, you will not be able to properly control anything larger than 680's with a SAFC because of timing advanced issues due to the amount of airflow you will be hiding from the ECU.

well im glad you guys informed me of this now all i need to do is fine a 95 eprom ecu any suggestions???
