I would not mess with trifecta, on my supercharger project it took them a month to send me a half ass tune that was extremely lean. Sent them a data log and 3 weeks later he emails me about how the intercooler pump is wired. I email him explaining how it is wired and he never responded. I gave up on him a week after the last email. Got it dyno tuned and it was good to go besides the clutch. Overall trifecta's customer service was horrible. I sent them an email about once a week and never got a response. If I were you I'd do whatever engine mods you have planned and then find a good dyno shop
