not running like an ls1
not running like an ls1 I have a 99 trans am m6 and it has all the free mods done plus borla cat back exhaust and slp lid. I recently just tuned it up and it still dont run like i think it should. when im in first gear at a roll i can punch it and it just squats and goes it dont even turn the tires. The car runs very smooth and doesnt burn a drop of oil but what is wrong why dont it even turn the tires loose unless i dump the clutch? Itll smokem all day like that but it should at a roll as well. plus when i am racing it and revving it to red line the clutch loses pressure and it dont wanna go into the next gear. Can anybody help me out and tell me what i can do or what is causing these problems? I have pulleys, slp long tube headers, off road pipe and y-pipe, denso plugs, msd wires, a tuner, and 4:10 gears that im gonna be adding to my car shortly so hopefully that will help it out a little bit. but i would like to atleast have a halfway decent running car if im putting all this money into it. Please help!! thanks
How many miles on the car? No they just dont smoke the tires all the time from a stand still or a roll. I have a 99. If you think your low on power do a compression check first of all.
it has 136k but i did a compression check and they all were fine. I ran some lucas injector cleaner threw it thinking maybe that would help but it didnt. The car does rock back super hard when i floor it but i figured it would cut the tires loose. They are only 245-50-16 HR II's so its not like im running street slicks on it. I dont know if this has anything to do with it but it does have the sway bar romoved and subframe conectors on it. Should i maybe try running a can of restore threw it?
My SS was the same way before I put LT's and ORY on it. Now it will break them loose like nothing. Before it wouldn't spin at all for some reason. I was guessing it was the tires being basically new and 17's. My old 99 Z28 would roast them from a slow roll in 1st and it was stock. It was also on 16's though. Get the car to a track and see what it does.
what rpms were you running when you punched it?if you were in the lower range,it won't spin the tires..
it's not like an auto with a stall,my old Z would fry the tires by just punching it,but that was due to the converter..
if it pulls hard otherwise,then i don't think you have a problem..

Cant hurt I guess. My guess is there is some residue buildup. Try sea foaming it. also just the outside weather will have an effect. Air qaulity changes with the seasons and it really has a great effect on power.
I thought about the sea foam but what should i mix with it to condition the seals? I have heard alot of horror storys about it but i have never tried it. I was about 2500 rpms when i punched it. It seems like other then not wanting to turn the tires over its pretty quick. I will give sea foam a shot. what do you guys think is up with my clutch though? I cant really run it threw the gears to see what its gonna do until i get that problem fixed.

Its hydraulic. Could be the fluid is low or when was the last time it was replaced? I dont think the fluid is bad but maybe? if its the original stuff? Could be on the way out, they dont always have to slip a lot before they go. I'd look into the hydro part of it first though. There was or is a drill mod to one of the lines, look in the stickies in the clutch section.

Well at my shop I just had a 1996 Formula Completely stock with 15K miles on it that is for sale and it would spin in first without even thinking twice about it. God forbid you gave it 1/2 throttle coming out of a turn.
My SS was the same way before I put LT's and ORY on it. Now it will break them loose like nothing. Before it wouldn't spin at all for some reason. I was guessing it was the tires being basically new and 17's. My old 99 Z28 would roast them from a slow roll in 1st and it was stock. It was also on 16's though.

. I wouldn't be so concerned with getting the tires to spin, it's better if they don't. 
My last car was a 465rwhp 422rwtq Z06 with 305 nittos and it wouldnt always spin the drs. the ls1s dont make a whole lot of low end torque. The engine in my pontiac has sat for 20+ years but will still break loose in 3rd gear (th400). Its all about torque. Its much easier to launch a car with less low end torque. I used to have a 95 formula and even when my z06 was stock i know there was a noticable differnce from my auto 95 than my manual 01 z06. My 95 would break loose 315 in 1st no problem with just bolt ons. I have an 01 duramax with over 700ftlb torque and it doesnt even spin the tires unless towing some trailers. Too many factors involved.
