Chime in if you're running a Performabuilt Lvl 2 4L60E
I'm thinking about going to a PB Lvl 2 when my stock 4L60E finally goes. It's money I know, but the assurance of a reputable builder putting my trans together is worth it. I have a couple questions about them. . .
-How is the shift? My factory 4L60E has Vette Servos and a Transgo HD-2 and it will chirp 1-2 in my boat at WOT, I do NOT want to lose this ability
-What kind of real numbers are they holding strong behind?
-Is the Lvl 2 overkill? Can I get away with a Lvl 1 4L60E in my Suburban?
My future mods will be single turbo setup with some sort of intake upgrade to handle like 6-7 psi, I'm pretty sure I can make something work, since most of the S/C kits for the L31s run 5-7psi out of the box on stock injector setup so we'll see about fueling, but what I need to know is what would be the better bet considering my weight and my FI goals for the future?
Thanks in advance for the help!

Well I had the level 3 and my truck weighs about 6400lbs with 35" tires. The 1-2 shift would chirp the tires even at part throttle and especially full throttle; very aggressive. The 2-3 was almost as strong and would chirp slightly at part throttle. I ran it with my 408 and blower which was 600+ and never had an issue for the month and a half I had that setup.
Still is flawless after 2 years or so of boosted life

I have a friend that has a performabuilt lvl 2 in his gto that runs 10.0x. He's at the track most weekends for almost a year now and has never had a problem with it.
