New z28, help!??

[hasenbonkers]

Ok just bought 98 z28, 86,000 miles. its automatic .Really fast in first gear. but when i punch it around 30-50 it just kinds of goes lil faster like a usual acceleration. (No screaming engine or kick in seat) ilike i said first gear, idk if thts how they r, like i doesnt really accelerate fast like i thought it would in second gear. Also really doesnt downshift on it own during then too? Ill try to get a video, any suggestion. Just seems like theres no WOT during second or 3rd?? I took it to mechanic he said he felt no problem, but ive been in trans ams and z28's. Any help please. thx!

30-50 in a a4 is kinda a dead spot.

If you just got the car I'd suggest giving it a full tune-up and change of fluids, unless you've already done so. Maybe you'll feel a difference, maybe not.

Common problem with LS1 TB's, search for Throttle Body mods on Ls1Tech or something. Wish I had a link for you.

Try adjusting the throttle cable, there's also a bump stop on the TB you can grind down so the TB blade opens more.

4L60 in the LS1 ftl. Talk about being dropped completely out of your powerband.

Re: New z28, help!??

that is the dead spot for the 4l60e. to make this go away, look at high stalls.

Dead spot between 30-50? I know if I floor it at around 40-45 it'll kick so hard my tires spin (granted they are slightly old).

on a a4 ls1??? im guessing you have gears or ****ty tires+other mods. on my car with 3.23's it will drop to 1st up to 32 or 33 (somewhere around there) and do this http://videos.streetfire.net/video/6...b10160f2a6.htm any higher it will go to second and lag for a second then go
