I have never understood why people think that a t6 is going to spool slow on a v8. I guess it depends on your definition of slow. To me 15 psi by 3700 rpms (like on my s480 on my 5.3) is very tolerable. Personally I want to be able to do 3000 rpms cruising without being in the boost, haha. Congrats on the results! Hopefully they let you run and you can turn it up a psi or two.

Log in this thread if I remember right. It was too fat and breaking up some, but should show how it is spooling...also has the tune.

Yeah that was the one. If you look, that was a 2nd gear I believe, but it hit around 15 psi at 3700 rpms. It was fine up until it hit that point and then it started missing really bad. I have since tuned out a lot of that by leaning out the air fuels as it comes into boost and giving it some more timing. It is spooling faster now than it was before! Car is getting better every time I take it out to tune on it.

Well did a bit more logging today. Look around 3:23. It is still going too rich and breaking up a bit, but right around 14.xx psi at 37xx-38xx rpm. This was done with the trans put in 1st gear manually. My tach agrees. I have not yet hooked up an auxiliary boost gauge though to verify map.
Edit: I realized part of my problem with the breaking up...I still had a bit of a JUMP in the VE table numbers after 3600 rpms. That is probably why it is breaking up so bad. I have knocked those down a good bit and hopefully it will be a bit better. I was quite honestly scared to go over 60% throttle with the roads a bit wet still. This thing does not have the stickiest of tires yet and likes to break the tires loose pretty easy.

End thread hijack. Sorry OP. But these turbos ARE amazing and I have always liked and used Borgs for the past 10 years. Previously on 4 bangers and now getting a big boy turbo to go on this little LS motor. I have not been disappointed in any way, shape or form. The larger Borg units like this one put together by Jose at Forced Inductions has been great.

New to this forum and I was trying to see what other people are making for hp and what time they are running. I swapped a 5.3 into my 69 firebird. All stock at 13 lbs at made 548whp....thru a zo6 cam into it and it made 587whp at 13lbs. Did a comp cam and pro flow intake and it made 633whp at 13. Ran it in the quater mile on 275 et streets at 16lbs and got it to go 9.98 at 137 the car weighs 3600lbs with me in it. Figured its making about 710 at 16lbs. Wanted to eun 18lbs but the wastegate blew open at 16

It's a turbo 400 trans....The first time on dyno it had z06 valve springs and 80 lb injectors. Other then that it was completely stock. Made 548whp. It's tuned using Eli live on the stock Ecu. This was 2 yesrs ago now it has a cam intake and better springs its making 633whp and I'm positive the hp # would be higher if i had a tighter converter. It has a 200 dollar B&M converter that was put into the car 14 years ago. It flashes the converter really bad. My buddies car with the same setup did 670 at 13lbs. He has a billet converter
