I have an L03 with a 94 f body LT1 cam, heddman headers, edelbrock TBI manifold, MSD 6A box, 454 throttle body, air raid spacer (ported so 454 TB blades are able to open) 350 injectors, i converted to a heated 3 wire O2 sensor, under drive pulleys, i have a Jet Stage 2 chip, its got 3.42 gears and a T-5. So for the question..... i know i need some tuning or atleast i think i do im so lost on that part the car runs good it idles good and the gas mileage is very good as well so i know its not running too bad. BUT i know i can squeeze more power out of it with some tuning ive looked at other threads and i hear about EBL and tuning with a laptop can anyone give me some guidance here i want to do it myself and i like to learn but dont know were to get started Any info will be appreciated

 

Start reading the stickies in the DIYPROM section.
EBL will save a LOT of trouble and time, but you still need to read.

You should start off by using a laptop to datalog and study what you've got right now.
You can also determine what mask your ECM is using, then study the hack.
Once you understand what you have now, the EBL will be easy.

 

After you plugged the ecm with the EBL upgrade:

That is ALOT of info i didn't even know what an EBL or how to datalog but i will buy the aldl cables for the laptop and try winaldl and start there

 

I see forged 355 in your sig, if you plan to use your EFI sistem on it, save the $$ for the ALDL cable and get EBL.
The data flow of the stock tbi ecm is little and slow, you will also need VRFPR wich it does not allow.

 

were can i get an EBL and whats a reasonable price to pay for one??? Tha 355 short block is done i just need heads and the plate for CARB to TBI flange cuz im using a edelbrock carb manifold. If i buy an EBL will it let me program the computer so it runs well without EGR???

 

Worth every cent. http://www.DynamicEFI.com/ Its going to take around 15 seconds to disable egr and flash the new calibration into the EBL.

 

Thats impressive what you can do witht that i will buy one of those instead fo the ALDL cables and it doesnt look to hard to instal thanks for all the information

 

For little $$ you can get it already installed in a ECM, unplug the old one and plug the new one. No down time.
