Camshaft/ TPI Stealth Ram

Would anyone know what Cam size I can go to without Freaking out my ECM in a 1986 Iroc with a Holley Stealthram, 58mm Throttlebody, 5.7L With a superchip? I have a Grind now that is made specifically for the TPI system but I want a little more rumble.

well its a MAF system, so its pretty forgiving with mods, i would upgrade the ignition system to handle the extra air and fuel. what cam specs are you running now?

I have an MSD 6AL, and an MSD coil, Don't remember the Cam size but I do Know it's from Crane, and It's for a stock TPI upgrade. I'm beyond this one now.
