i got a 99 civic si ...sc50..built bottom end and what not..last year my car was tuned with 440cc injectors and hondata...right now during the break in im just running the 440's but i got some 650's.

last year the night before i tuned it i had someone put in my 440's..it ran VERY rich and died acouple of times at first but then i just made sure to keep the engine reved alittle when i was stopped..my question is ..can i pop in the 650's or will that be way to rich to even run? my car is tuned for 440's so i thought it might be ok put the 650's in before i take it to get tuned cause i dont wanna pay the shop to put them in. thanks

 

dont do it...........you will run way rich and could possibly cause engine damage.

go to your tuner an hour before. bring your own tools and swap out your injectors and have your tuner make you a new basemap for your new injectors.

 

are you nuts?

 

well he is from the land of 10,000 morons or whatever
