Stage 2.5 cams and tuning

[Rolltide1006]

Hey all! I have a 97 GT and had the motor rebuilt. It will be finished and running in the next week and was curious on tuning. I am installing CMS stage 2.5 blower cams in my rebuilt 4.6. I know the car will run, but will I be ok for a week until I can get it dyno tuned? Also I don't have the supercharger yet so it will be N/A at first. Any help or advice is appreciated! The motor has forged internals minus the crank, arp fasteners throughout and PI heads with upgraded springs and valves

Do you have a wideband to monitor afr? You should be fine driving it for the week. If your worried about it, ask the tuner to write you a startup tune so you don't burn anything up. I ran my old pi swap with stage 2 cams for a few weeks without tuning.

Ya I don't have anything but the stock ECU with the stock tune. Hoping I will be ok. I'm going to make a few phone calls in the AM [emoji1303]

idle may be your biggest issue.
