Thats the only problem I have with DOHC engines...no low end torque, the topend is nice, but I just can't stand now having instant 0torque. I was just born to drive a pushrod engine. I just have to have low end torque. However, thats the problem with my car...no low end torque...it won't spin the tires until 10mph when the turbo spools, yeah when it does break them loose at 10mph it just goes crazy and smoke rolls out, but still, I need more low end torque BEFORE the turbo spools. Time to open up the exhaust to help the turbo spool I guess. I feel for those DOHC guys without much low end torque.

Jim, do they make headers for the 4.6 Northstars??? If so, do they bolt up to the 4.0L??? I'm thinking probably not or you wouldn't be looking, but worth a shot.

woulld headers on a NA dohc take away torque?

it seems like if i turn traction control off, i have less torque, i can barely get the tiniest squirk from the tires. with it on, i can get some, then the tc kicks in and cuts down on it so i dont get much there either. damn olds, they give us the strongest fwd transmission, but wont let us lay just a lil smoke. im getting that chip to get rid of this stupid torque management

Isnt tq managment disabled in 2nd gear?...with TC off and power trans on, you can benefit from the 4T80E

tq management cuts down the power at shifts, according to wes at ecmprogrammer.com it also makes it so aurora'* dont release all of there power off the line. then there'* also the factor that if you leave traction control on and floor it, you geg some spin, then TC kicks in slowing you down, but if you turn TC off, it takes away so much power you can barely squeak the tires

stupid gm
