Need some Tuning Advise???

Guys/Gals,

I am trying to tweek my LT-1 (383) setup and need some advise on the following TunerCat tables:

My setup is a CC305 cam, AFR 195 heads, 30# injectors, 58mm TB, mid headers, etc...

The columns I need advise on are:

%Change to Fuel/Air Ratio Vs. RPM at WOT
%Change to Fuel/Air Ratio Vs. Cool. Temp at WOT
MAF Sensor Calibration Tables (1-4)

I am pretty knowledgeable with tuning, however I don't have access to a Wideband O2 and am trying to save the 500+ bucks for a complete dyno tune. What I am looking for is some recc specs for these fields with this Cam and setup as all I have found is a 383 .bin file for the CC306 cam and these settings probably won't work. Any suggestions?

Thanks!!!

buy a wide band, an engine is an air pump, some pump more than others even with the same displacement and cam. you have too much money in this to screw it up now.

Unzip this excel file and copy and paste your % tables into it. It will give you an idea of what WOT A/F you are commanding.

Thanks for the file, great little excel. I'll give her a shot, but might be all I can do without a wide band so probably best to save up for the dyno tune down the road.
