90mm T/b Need Help!!!!
Who makes the best 90mm T/B now? I have a old Williams? about 9 months old, and was never able to get the idle to stablize. It idles at 2100rpm till the mph on the HUD reads 0 than drops to 950rpm. Two differnt tuners both say it might be the t/b. Its on a 432 CID with a fast intake and a T-REX cam 110 lsa. Any ideas? I tried the LS1 fourms but since they use a cable they don't have this problem. Thanks.

Nick Williams has a new improved version of the 90mm T/B that is supposed to have taken care of the issues you mentioned.

I have a new 90 mm from LG and it has a screw adjustment; if the adjustment is off the engine won't run right. The screw adjusts the throttle blade opening and the resulting sensor value. The allen set screw is on the motor side and has another allen set screw to lock the first.
