I'm not looking to do an intake swap or a spacer. The 03 tahoe has a new throttle body, and I will be using the original intake. I am building a 5.3 longblock and swapping the intake over, but wanted...

This is just a theory, but wanted some input from those that have had more time with tuning. This is what I have going on. 2003 Tahoe with a stock Gen3 4.8 DBW. I am upgrading the 2003 from the 4.8...

It is the stock fuel system. 25gph pump and inline filter. I haven't needed to upgrade the fuel system until now so I'm not sure what the best direction to go is for my setup. I am assuming by your...

I am guessing when you say filter you are talking about the inline filter on the frame rail? I only ask because I had replaced the pump a few years ago before I did the upgrades, and the pump also...

You can disregard the scans. I have found the fuel pump needs upgraded to finish tuning. That being said does anyone know what size I can go with that won’t necessitate upgrading the return line?

I have been able to use the day to get some tuning in and wanted to share progress. The last time I was at this point I had the 30# injectors in and the duty cycle was maxed out. I am attaching the...

I have updated the designated tables per your Data. Its attached if you want to make sure I did it correctly.

I am going to wait until Friday to get back to work on the truck. My son put the 30# back in and loaded the corresponding tune back to the truck. As for the information that you have graciously...

12613412 Are the injectors I installed. I'm sure you already know which ones they are, but to be exact they are GM 50# flex fuel EV6 from GAP(GlennsAuto Performance). When I added the flowrate vs KPA...

I was hoping this would be an easy trouble free injector swap, but apparently nothing I do is going to be easy on this truck. I changed the injectors and added the adjustment in the editor for the...

Thanks Squirrel. I just wanted to make sure I wouldn't be surprised by the scan with a major jump to the rich or even a lean issue for some oddball reason. My son has been driving the truck for the...

I have already worked with a couple of you with tuning my 99 silverado. I finally found time to get my 50# injectors in with the updated injector data, and wanted to ask before I start the tuning...

It is suppose to storm in my area this weekend so I may have to wait a little longer to get another scan. I wanted to ask though if the converter clutch could possibly cause the same issue?

I can try to get another scan but it doesn't do it all the time. The transmission though is a fresh rebuilt unit that I had upgraded to level 2 by performabuilt. I will post something as soon as I...

Sorry for taking so long on posting the tune. Alot going on in the driveway.

I don't have a scan to share at this time because I think my question can be answered without one. I have a new built 4l60e transmission in a 99 silverado. I have done the bluecat tune adjustments,...

I sent you a PM and I will lower to 425 and share an update.

I understand how bluecat works and I have made adjustments. I included the scan so I can get some direction on how to interpret the TCC lockup. I'm not sure what my readings need to be for TCC slip...

I am looking for advice/guidance on my trans tuning. I am working on the engine tune as well but on hold for bigger injectors. So I'm going to get to work on the trans while I wait. I'm not looking...

I bumped the O2 rich lean and also added some transmission channels at the bottom. I went through the scan again and watched the lambda read out and it is still a little above the 1.00 commanded but...

I made the O2 adjustment and set up the scanner using the screen shot you shared. While I was in the editor I started looking through the trans tables and they were all over the place. Once I get...

The truck I am tuning has the primary and secondary VE tables. It is the P01 PCM and I was having issues figuring out why my changes weren't working. Rabbs88 helped me and I set up my scanner to tune...

If you are doing VE tuning it is best to do it in speed density with STFT and LTFT disabled until you get the cells +/- 2%.

When driving plan your route so that it allows for time to roll on and off of the throttle easy. Sudden acceleration/deceleration causes the scan to skip cells. If you can add in to the hills into...

Scan with your O2 changes. I also made a slight change to the base idle table and idle AF to fix the in drive characteristics. The wideband is still reading lean but the motor did run a little...
