I have a 99 Camaro that I bought and was untuned. This is a whole new experience for me so any info would greatly help.
When I picked the car up it ran on SD and needed alot of tuning yet. The way I was shown to tune it was to take the negitive numbers out of the histograms and subtract them from the tables. It seemed to work as I was racing the car and it was going faster every pass. Here is a log and scan of my last pass.

I also drive the car on the street and was told a maf would make it more user friendly so I installed one and it seems to run ok other than while driving at a steady RPM it will occasionally cut out for a split second. I also loaded a tune and scan with the maf.

The engine is a 408 with Agostino Racing Engine stage 3 heads. Cam spec's are 243/253 617/642 112LSA, Edelbrock Victor Jr intake, Accufab 90mm throttle body, Wilson 90mm 90* elbow, SVO 42lb injectors

Any help would be greatly appreciated.
Thanks,
Shane
