I wonder why 5lb's of boost on the front mount is just as fast as 10lb's on a rearmount? You think it's just the perception because it hits harder? I don't know why your front mount would make 100+ more hp then a rear mount.
I'm also questioning that maybe there might be a back pressure issue with the TC78, so that when you turn it up to 10lbs the back pressure negates any gains?

Yeah, its weird. Gonna do some more logging through out the week and see if we can nail down the issue. also going to rear pressure test my cold side.

if your running just gate pressure ive heard the gate can begin to open at lower boost levels causing issues building boost in first. try using a boost controller to hold teh WG closed until desired boost level

Currently have the manual controller from Halman and its setup like their instructions say. Seems like if just move it to the top of the wastegate and and use it for pressure on the gate then it should do the same. i would think.

Also, if i could do it over again, Precision all the way. I dont have anything against this turbo, but everything i read from people switching tells me i shouldve done that in first place!

You should be able to load a a4 shift table to your pcm and run the wires to the trans. But pin outs are different for the 4l60 and 80e. Don't say that about the Turbo! Your gonna make me second guess my choice of a tc78!

I just went out and did a quick foot spool video on the brakes for a guy who wanted to see what was happening on my gauges etc.
i was able to stall upto 2200rpm on my 3200 stall, but i had to yank up the E brake to make that happen, on the regular brakes, my rears simply arent strong enough to hold or it just pushes me down the road if the backs are heated up.
So, ive got other issues, i think we are gonna try throwing some timing at it in stall up area and try to build some torque.
if not, ill have to figure something else out.

Really no updates, Still waiting on a nice day to do more tuning. Kind of sucks, also gathering parts for a 4l80 swap since this 4l60 already showed me a sign that it might not last alot longer.
This will be trans number 3. Hate it, oh well.
And other then that, found out how my engineering sucks during the first plug swap, wasnt fun!
Got it done, but wasnt fun!
Anyway, im sure once i get some more tuning in ill get some video. Im also building a mount for my digital camera to go on my head rest for video action
