Not sure how that works. With mine, it was power and the lack of it causing TC stalling. The hand throttle changes none of that, it just gives you a free foot to play with. I just could not get up banks at all. I think I have a vid of it somewhere. One small tweak and a little more fuel and I was sorted. I had new injectors in as well and that didn't cure it. I guess after nearly 20 years the system goes off the boil a little. I could have messed around with the other screws but advice was you can't ''boost' what isn't there. Small turn and woof. I had bigger tyres on then (than standard) and maybe if I'd stuck with original 31's or whatever, it might have gone up. Going to 33's changes the game doesn't it. Now on 37's and 4.56 diffs, I still can't always get up, but the TC doesn't stall.
