Thanks for the quick reply. Do I need to have it dynoed and the numbers sent off for them to know base line and then dynoed for them to know adders and have them tune appropriately? And I assuming like the hypertechs or whatever for 20 years ago putting back to stock is simple through the hand held? I just thought I’d try something different with this old ass Hoe. It’s been fun messing around and playing with it. I love the NBS interiors and having this thing in the family since new I know it’s secrets and figured it can be fun. I have a grip of trucks ans all my old cars. So I thought a NBS but Tahoe could be fun. It has been except: the ride is dog shit. It has torsion delete, full adjustable coilovers, all new bushings, sway bars front and rear, DJM rear kit, Tony’s springs, belltech rear shocks (DJM extenders), adjustable panhard, belltech front spindles along with the coilovers. Only other thought is full moog make over up front along offset a arms. But I’ve have the full spohn treatment in the real (kept the panhard) and nothing is helping . I’ve had some crazy ass SEMA builds that people thought wouldn’t work that rode and out performed this and many other trucks. One won autocross and Goodguys and SEMA awards. Sorry to sound like an ass. After my meds and alcohol just hoping to find help this great forum seems right give a lot of others. Thanks again. I’ve belonged for along time but never share. Love the threads and pictures. One is marks (the machine and the beast). It sucked caused I read each post in it’s entirety and during which I was I like no don’t wanna get this , and save your money for this, but I was so far behind I couldn’t help. Great job with both just wish I could’ve helped. Sorry for horrible grammar
