hey guys i got a question?

i put dsm 450cc injectors into my ca18det. i noticed the tips of the injectors are slighty shorter but other than that they are the same, i also have a 300zx mafs. my problem is that at idle and at low rpms up to 3500-4000, my car runs like **** and sputters, but after 4 grand i runs like a bat out of hell. i have my superafc minus 50% at idle. and it still runs like ****. any one have any ideas?

thanks brad

Have you had it put on a dyno at all, maybe then you will be able to tell what its doing.
