Default SMC injection

Did a search, found nothing. I have a SMC kit on my 95 LT1, and would like to know more about how to use this kit. What is the best stuff to use, mixture, etc. Also, I would like to learn more about how to tune this on my D-1SC non intercooled kit. It seems like it makes my car go flat right now, so any help is much appreciated. Thx!!

If you're running pig rich, reduced timing, and the methanol/water injection then that would explain it.

You honesty want to run a 50/50 mix of meth and distilled water. There are alot of reasons for this. Most of my users inject right after the maff. His kit probley needs to be placed in the same place as mine.

This is some good info. My kit is setup with nozzle located about 1.5' from my tB. It is located close to the blower, but after the maf because my kit relocates the maf to under my front fender splash guard, which is a lot further
away. I was told by the guy I got my kit from that I needed to use a 50/50 mix of denatured alcohol and water, so that I did.

White2001s10 you seem to have described my car well. I have a mail order tune for the blower being installed, and it seems to be very rich from idle and up. I live at 5,300 ft altitude, so I bet the tuner left it fat to be safe. In addition, I see only about 6-7psi boost on a good day. At the track with the injection, I ran 12.10-12.20 at 7500 ft DA. Then I turned my injection spray pressure way down and ran an 11.80 under similar conditions.
