turbo lag

I know exactly what your saying Josh. When I first had my charger installed I had the same issue, lugging 6th gear, especially trying to pass a car. I would have to drop to M and manually shift to 5th and it would spool and go then. I have a trans tune now that takes less throttle input to downshift from 6th to 5th. Probably about 15-20% and it downshifts. This would be annoying with a stock or quick spooling smaller charger but with this big single it works great.
Here's rolling into it in 5th with the TCC locked. The turbo never lights and I'm doing almost 80 when I let off. I was trying to not make it downshift and I ended up around 80% throttle.
Turbo is a Bullseye s375/87/.90 with a billet wheel and 3.0 cover.

I think I found part of my spool up issue... waste gate was stuck partially open at all times relieving drive pressure off of the 366. Haven't spent any time on the road yet to test it, but i'm sure it will be better now. :thumb:
Spool up is amazing now! After driving it over the weekend. Huge difference! With my inexperience I guess I just never realized there was something out of wack like that.
Cruising in 6th at 1600-1700 and you can just roll into it no prob, lights and goes.
Definitely a lot more torque down low, rods are going to be doing the limbo.
Poor JoshH was all over the tuning. With the waste gate cracked open all the time it was like spooling 1 huge turbo, and his tuning had it pretty friggin good...now the tuning with the waste gate fixed is just flat retarded bada$$! Light puff of smoke and its off like a rocket!! Huge thanks to Josh for helping so much!

Josh said he was building you a set! Exciting!
Now you just need to find that 4wd donor :thumb:
Russ are you running a Back-pressure gauge? I am debating where to waste-gate or not. I have less fuel and will not be pushing it as hard....
No sir, no way I'm driving these hard enough to have high drive pressure. If you are running a similar setup to mine and less fuel, I wouldn't jack with a waste gate.
I have a T4 366 on the small turbo.
