safe to break in motor without tune?
well ive got a 383, 11:1, le2's, big HR cam, etc and i am wondering if it will be safe to run my car at all without a tune ( 15 mile trip to tuner) also, i have a pcmforless mail order tune for a full bolt on/cam only car. would it be smarter to put that in, or leave it as stock

If you run that without a tune, not only will it refuse to idle, but it will run extremely rich (which can wash out the rings). I would personally trailer it there.
No idea on the mail order tune that you have.
One would think a "kinda close" tune is better than a "clear out of wack" tune. But I do not know.

i know man im thinking the same thing. like logically it makes sense that it would run closer to good on the other tune but i know if i do, something will blow up, then when i post it, everyone will be like wtf why would you do that you dumbass lmao

stl- the tune is for stockers, i now have svo 30's 
bomb- i can.. id just save the 55 bucks for the uhaul trailer by driving it ( im poor $55 is a considerable amount of cash for me at this point lol)
steve- can you do that for a 93?

If it's at least not tuned for the 30's, I wouldn't drive it. Or, you could drive it to the shop with the stock injectors and switch them out when you get there. Too bad it's not a 94/95 I would send you a starter tune.

Depending on the size of the cam, it may be tough to tune it remotely and your only choice may be to trailer it.
I'm in that boat right now, but my cam has 34* of overlap LOL so it's a
little tougher to tune than your typical HR street cam.
I'll be trailering mine from KC to Tulsa in a few weeks.
The base tune was simply too rich to drive (less vacuum than expected).
$55 for a trailer is a hell of a lot cheaper than ruining a new 383.

thank you guys for helpin first off,
what i mean by that is my cars a 93, its obd1 and i was under the impression you cant flash my pcm like the latter models
so what your saying is bring the pcm itself to the tuner and he will be able to give it a base retune just to get the car to the shop? im sorry if im soundin dumb here i was just under the impression that to tune an obd1 car you had to install a modified "chip" which is like what i have now, the mail order "chip" sitting in my room. i didnt think you could just wipe out a tune and form a new one like on the obd2 cars
james- i totally get what your saying, $55 is chump change when you melt down a forged 383
and yea i wish it was a 94/95 because i know u can just reflash em and i appreciate u offering yours to me
