ROM does not affect signal strength, only the radio does. I will say though that I have an Airave so I have full call signal in my house, on stock Sprint ROM it shows all 7 bars, when I flash a custom ROM (even adding the 7 bar cab to Mighty) it shows 1-2 bars. When I make or receive a call 1x strength shows full but with the phone just sitting here it shows 1-2 bars. I have always figured it as the custom ROM's are showing data signal strength or something, but it definitely has never affected my calls, texts, data or anything else on my TP or now on my TP2.
