I'm thinking the Trinity would be overkill. I'll need a tuner to pull timing for my 100-125 shot and install a 392 cam (I heard it was easy to tune for a pro). Arrington or Modern Muscle would likely do the custom tuning. Doubt I'll ever go farther than this. Would the Intune work for me? Could an Intune also be used to tune a procharger too? I guess I'm trying to see what the limit is for the intune. I have a Trinity on order but feel like spending more wouldn't benefit me. I already have a diagnostic scanner and my STP gives me the extra gauges on my screen.
