58 mm TB's are more typically used with more cubic inches, bigger heads, cam, long tubes, etc.

As C4vvetrn< Just posted. The 58mm TB on a stock??? LT1 is not economical. "unless it was free" And honestly. Needs a PCM RE-tune. re-mapping the AFR. Yes. I have been programming for years now. Forced to learn. From many 3rd Gen f-body Builds. The 94 - 95 PCM is much easier. to tune. you can program straight from the OBD1 "ALDL" port. that actually looks like a OBD2 port. I have a stand alone PCM program harness & power supply to eliminate the crosstalk. Within the 94 - 95 PCM, CCM & related computers. Also on battery back-up. The downside with this system. step one. The program erases the flash memory. If ANY errors occur. It's all over. De-soldering Two AN- flash is now required. and re-flash. them with new individual start-up files.
If you installed power adding parts. requiring. larger injectors. Yes, your PCM would require a tune to match. Larger injectors.
It would take a fairly significant power HP increase needing larger injectors. What stage level is your LT1.
I use CATS> http://www.tunercat.com/
this is a one~ stop & shop. Handling. everything required. But it will take 1000's of practice tune's and research. for someone. starting at ground. Zero.
PS. I wish this wide band was available. when I purchased my auto meter.

My lt1 is at stage zero just bought it i am a mechanic fyi just to say im not a full noob haha.
The previous owner did exhaust and air filter lid cut and i did the throttle body coolant bypass.
Im trying to make a game plan of the best and inexpensive way to gain around 40 to 50 hp .
I was thinking a new fuel pressure regualtor to lean out the fuel ratio and a Wideband gauge setup . Thoughts on throwing in a 52 mm throttle nody while doing that and then getting either a dyno tune or a re map .
Thoughts please and or any other route i should take

Yes. Sir. 2,000 - 5,900 RPM. I also increased my oe PCM rpm limit a few points. Data master is a logging utility. after you log a session. you enter your start & stop point. populate your cars info. weight, gears. Ect. in the dyno feature. and run. Or hide. LOL
