1BADGTS is correct in what he's saying here as far as the reliability of an engine that was designed from the ground-up to have FI vs one that was simply built to be reliable NA (the gen 5 V10).
I cannot blame mopar for not releasing a S/C kit. Let's pretend that the kit yielded 100% reliability in the same testing extremes that the NA engine was subject to - even if that were possible, it would be a losing proposition from a business perspective. They would not be able to sell enough of them at a reasonable price to break even, let alone make a profit.
How many Gen 5s were actually sold to customers to date? Isn't it under 3,000 total? I'm talking about actual deliveries to buyers, not dealership inventory. Let's just say that it was 3,000 and that 10% of these buyers decide that 640 HP is "weak" and they need a blower. Ok, that's only 300 customers...so even if the kit retailed for $15,000 (a bit high for a blower kit), you're looking at $4.5M in sales on the optimistic side. Subtract material costs, R&D, certifications, testing, govt red tape, salaries/wages for employees, advertising and logistical expenses...so of that $4.5M in sales, the margins would likely be slim to none. If you were to sell the S/C kit at a more realistic price, say $7,500, then it would probably result in a net loss per unit sold.
I think there are going to be tuners who offer FI options for G5 Viper owners, as they do not need to meet the same standards as a large automaker does...but I feel like my Viper is very well balanced as is.
