383 Installed

[turk]

Finally got my '99 back today. I had a 383 GM performance engine installed. I picked it up and I can definitely tell it has more power, but I know there are more ponies there that I am not able to spur. I am currently in "break-in" mode as well.

Couple questions:

Anyone else on here do this swap? If so, are there any quick fixes to increase the horsepower. I didn't know if a programer would help. I am running stock gears, stock intake, and stock exhaust.

Should I have it Dyno Tuned?

ofcourse theres power to be made.

Full exhaust, LT to tips.
CAI.
Full roller rockers.
Higher stall converter.
Under drive pulleys.
Obviously a full tune.
Etc...

Just decide what your budget is and go from there.

Best bang for buck is to get it tuned. Go with Black Bear and get a life time tune.

a dyno tune. Been through all this with my 383. a custom, dyno tune is really the only way to go

Would you consider the Black Bear tune a custom tune?

I don't know of anyone around that has a dyno... I'm sure there are some close... I live pretty close to Joplin, Mo....and then finding someone who knows what they are doing is another thing.

Black bear is but a mail order isn't going to cut it. if he did it in person that is a better option. A dyno being the best option

Thanks guys... found a guy within 45 minutes that custom tunes and comes highly recommended.... will let you know how it turns out.

Make sure to get all the bolt ons you want installed before you take it to get a tune, saves money from having to be retuned again

That was my next question... thanks.

I was thinking of changing my exhaust next year... probably should wait on the tune until I do that?

I was also thinking of changing my gear ratio and I'd like to wait on that due to $$$... that should not affect the tune, should it?

the pcm needs to be programmed to know it has a 383 so as to get more from it. blackbear should be able to take care of that easily.
