Hey Duane! I'm working to solve the issues one at a time...swapping out the JBAs to Dynatech LTs this week, and will probably have to do a custom catback, eventually.

Looks like I may be doing the 4L80 swap sooner than I had hoped.

Its not bumping the limiter since I have it shifting at 5800 and the rev limiter is at 6500. The engine will rev fine but there is no power being made there at this time so why go there, right? It just revs a little higher during the 2-3 gear shift.

It did not do this with the old tune, and since Rick (Synergy) started fresh with a "stock" rather than trying to figure out everything that the last tuner changed, I'm hoping that the "shift delay" can be tuned out.

Rick just moved his shop, and soon as he can accommodate, I will get it to him to check.

 

I think you should hit 110mph if you hook I hit 109 and ran 12.4, I am going to the track in the morning with my new mods 4l80 ,inercooler ,410 gears ,and a 100 shot but i will run it straight motor 1st run and see what happens but i took some timming out for the nos, if you do put an 80 your truck colby make sure you put in a lock up switch it will help your mph. good luck.

 

Geez, your bus should really rip now! Be sure to report back on the new results...I'm eager to hear how she does!

I imagine that I will end up with a 4L80 sooner or later...and I will be sure to have a lock up converter when I do.

 

you going ot the track next week. I got hte yank 3600 in my wifes and this aint no joke!!!

 

Don't know yet. I have no reason to hit the track again...have not made any changes worth testing, and still have not made it to Fremont to have Rick check the trans.

 

Oh ok tell me when you go again id like to run you on motor then on a 100 shot

 

well the results are in i broke the tranfercase right off the line 1st run second run i ran in 2wd all motor and hit a 12.2 3rd run 12.1 at 115mph with the nos in 3rd bad start. i want to hit the nos right from the gate but no traction with my 275/55r20 street tires still waiting for my drag radials then i will for sure be in the 11,s and i also weighed my truck she is 6010lbs with me in it here is a video

 

Sorry to hear about the T-case BUT great runs!!! I'm amazed that you are that close to the 11s. The way mine is running I don't see me getting there without nitrous.

 

Wow!! Impressive!!!!

What are your mods?
