The ONLY exception is the FACTORY setups like GM's Cadillac and Corvette engines for example because the computers and sensors are designed for them.
For the record Mary.... My last toy ran low compression with a D1R Procharger making 18-20 LBS of intercooled boost. The engine featured forged pistons, premium rod bolts and main bolts, LT4 heads and intake and 60lb injectors with an FMU which gave me 120+ PSI fuel pressure under boost. I ran it one time thru the 1/4 mi. I spun thru 1st and 2nd gear and managed a 10.12@138mph going thru the traps in 5th gear. I ran 7K thru the gears with the 355. After my first run I was told to leave the drag strip and not come back until I got a cage rated for my speed in it. This car had 9's easily in its grasp but I felt my grocery getter would be too hard running around thru town with the added safety features added to it. Mary, this is what experience can do for you with 9:00-1 compression with mostly stock available Chevy parts and the mild LT4 cam.
Using power adders like a supercharger, turbo, or nitrous is basically the same as running high compression since these power adders increase compression. I'll give you a hint.... too much compression with the nitrous. Wrong fuel blend. Wrong air fuel ratio under boost. Wrong tuning.
