The BBK 62mm throttle body that was on my car when I bought it is pretty much junk so I’m replacing it with a Posi ported stock tb and plenum. So my question is do I just make the 2 hour drive and go back to Lidio at alternative auto to check the air fuel ratio or just drive 20 min to a local import tuner shop and do it there?

I took it to the tuner shop soon after I bought the car to check for safe a/f and to see what kind of power it made since it didn’t come with a dyno sheet. If it’s going to definitely need to have adjustments made I’ll gladly drive the extra 1.5 hours so I know it’s done right.

My Eaton is ported but I don’t know about the plenum. It was done by a local shop near the previous owners house so I don’t have any info on the port.

Throw a wideband on your car and then install the new parts. I'd the car runs leans, or you experience drivability issues, then retune.

What kind of tuner are you running?

I don’t necessarily want to add gauges. I have an SCT 3000 but the car isn’t currently tuned with that. It needed to have some adjustments made a few years ago and that’s what the shop I took it to used but has since been tuned at a different shop without a handheld.

A wideband is cheap insurance on a car running forced induction at higher levels. I get wanting a clean look, but it adds peace of mind. Not all tuners are capable of making these cars run safe under high boost.
