F35 clutch is must
Slush box not to sure be honest I'm around 360-380 ft lbs and I feel my auto is at limits

 

Oops,meant.3.29. I thought the auto was good for about 400lbs of torque and about that in HP. 4.29.... That was my '88 Mustang

You can upgrade the plates in the tranny. I forget from where.
And the auto.runs the 45 not the 35. A quaife LSD would help as well. The 45 Much lower pain threshold, but with 10-15 percent loss in the power transfer, just might be enough to keep all the parts where they belong. I don't think Bill will sell grenades, but at the same time I'm glad Bonnie isn't the lab rat on this.

 

Honestly I think the stock trans is good to about 500 ft-lbs if you drove smart. If you tuned it to have soft shift points and didn't drive like an indy car racer 24/7 I think it would last for quite some time. Seems as though the manual trans in the lnf cobalts can go at any time if driven improperly all the time but the manual trans in the lsj cobalt and the hhr ss seem to hold up a little bit more.

I'd definitely invest in a clutch though like Ecotec said

 

I drive mine like stole it though lol
I would power lower my shifts back down and maybe add back torque management for above 400 ft lbs

 

3.91 on the auto, 4.05 on the ss 5 speed.

3.91 is 2.4

2.0 is 3.29

 

Still waiting on a tune? If so that's ridiculous

 

Only issue I have with this package is it uses trifecta..... His tune for my car was slow as ****, fuel map was way way way safe, he didn't seem tune for my driving style at all

Now that I'm hp tuned by James I wouldn't be surprised if I'm low 13s as is maybe high 12s on slicks and remove spare and rear seats

 

Same here.

I wouldn't be surprised if this setup only puts down 350–365 due to trifectas weak tuning which might scare people away thinking its not worth the money when that's clearly not the case at all
