A/f question????
Fuel gets in the ring lands and when it fires off it will lift it, from there it will loose compression and alot of bad stuff from there on out.
dont ask me how I know.
What A/F does the car like on the motor?
12.0 would be alot closer and safer IMO but some people will tell you I dont know ****.

My car on the motor is 13.2
Add 42 more RWHP and 66RWTQ to the numbers I PM'd you earlier with the A/F on the 150 shot at 12.1-12.3 across the RPM range...
If it makes more power ther I'd run it ther for sure.
My 150 shot we run at 12.5 A/F .... you should be checking the plugs to make sure but 150 shot on a built motor is not much N20 at all.
Plugs are autolite Ar94's and they look perfect. I pulled all them and checked them over with a fine tooth and comb.
The car has no DCR either with the camshaft..
lgs hey man.... off the topic but i just got a 99 vette... how do u like the lg headers... and how were they to put in

Most guys I know generally run 11.8:1 with the gas, and these are stock bottom ends. Some tuners run 12.2. I think this is a tad lean but as long as you pull timing should be OK.
If you can get it to sit on 12.0:1 nicely it would be a good mixture.

Every motor likes something a little different but yes if your car like 12.7 to 13.0 on motor there is no reason a 150 needs to be at 11.7-11.5
My car likes 12.7 on motor and we run the 150 shot at 12.5.
Not saying everyone should do that but 11.5 is on the other end of the spectrum. You would probably never hurt anything with just a 150 shot with either tune up but your leaving HP on the table running it that rich.
are you talkin 14.7 wot? Mine runs about 14.6-.7 cruising, but 12.8 wot n/a. 11.7-11.8 on the bottle. If you are running that lean wot n/a, you must be running a huge fuel jet to bring it down that much on the spray.
