Tune
Hi everyone, I’m a novice at this tuning, but if I can ask a question. I just had my 350 replaced to a 383. Do I need a new chip in the emc? The car starts but runs very rough in idle and dies when I put it in drive. I’ve heard I may need a new chip in the computer to run the 383. Any help would be appreciated.

Check out dynamicefi. You can be self sufficient. If you go a different route at least you have the newer computer so there are tuners out there. TPIS did my 85 and did a good job but it did take a while.

Yes you will need a new tune. What injectors did you put in? If it is stock, talk to the tuner and see what he thinks of your setup. At this point, I would definitely go with dyno tuning or tuning via data logs.
