new 383...tuning problems
ok I posted a thread in tech/performance but i figured i would post it here to..
ok my new 383 is in and running but I have some major issues.It seems to be kinda sluggish from idle to 3,000 rpms then it just falls completely on its face. it misses like crazy anywhere above 3,000..so toay I stuck 30lb ford injectors in it because I thought maybe it was running out of fuel on the big end.the injectors that where in it where 24s and I didnt realize it till I had the rail off and in the house.so I went ahead and switched them anyway and it still keals over anywhere above 3,000.I do have a ajustable regulator and i sent my fp at 40lbs running.I have not got a new prom for it yet and I did have to advance my timming (advanced 15*)and play with the set screw to get it to idle and my tps is set at 56.
I pulled 3 plugs and they are back as heck..it is running way rich but would that cause it to fall over anywhere past 3,000 rpms?
also where can I get a mail order tune from????thanks

If you have a 91 speed density car, you need a chip burned right away. Dont even drive it. You can quickly destroy that motor. Speed density cars are very tempermental when it comes to mods. Especially since you have a 383 with a decent cam in there. Get you car to a local tuner asap and get a custom chip.

Sounds like you went from really lean to really rich.
When you had the 24's in i bet the gas pedal felt like fish bitting at a hook didn't it.
