98 gt tuning after mods

[Reds7ang]

So I’m sure this has been addressed in another post but tuning is new to me. I have have changed some parts and the vehicle is running extremely rich at this time and is not driveable. I’m currently running shorty headers, 70mm throttle plenum, screaming demon coil packs, victor jr intake, and underdrive pulleys. I’m sure a tune is required for all of these changes. My question here is will a base tune through my diablosport work to correct fuel mixture or will it need a full custom tune? If a full tune is required is there anyone on here that would be able to provide that if given a data log of current readouts?

I feel like the piggy back chip type tunners are slowly going away
I am switching to the megasquirt type of tuning
And be done

canned tunes don't usually account for mods. some may a cold air intake, other than that, a custom tune is needed.

Choose the custom dyno tune. Its a bit pricey the 1st time. If you have more mods you want to do, proceed with them to maximize the tune costs.
