torque converter suggestions ?
Im having trouble deciding what torque converter to get .Its 100% daily driver .Only mods are a predator tune /k&n fipk. It also is on the pilot sport runflats. So I ask what converter would give a decent sotp feel but wont blow my runflats away. Thanks to all those that answer.

IF you weren't planning on doing any other mods, I'd propably stay with something in the 2800 - 3200 range. A tune afterwards would help too.
you should be able to find one in the C5 parts section for a good price.

You do realize you don't need a different converter. If you want one with a higher stall that doesn't cost a lot get the one from the GM Astro Van. Its $225 or so and will work well. Do a search on Mike Mercury's post on this, it has the part number in the post. I ran my stock converter with a 3:42 rear and 450 rwhp for 3 years and 60K miles on the combo with no problems. It also ran 11.2 @127 at MIR. I sold the car last week for a C6 Z06 or I would still have it. You will get the best SOTP out of changing the rear to a 3:42. Might as well while your down there and have it apart. You will loose 2 or 3 miles per gallon worst case with a 3:42 rear.

11.2 @ 127 sounds like a supercharged car? if so, they don't need a different converter from stock. Although a higher stall (within reason) would benefit it as well.
Didn't know an Astro Van converter would even fit. But since it does, it will have higher stall because it comes from a V6 which doesn't produce as much torque as the LS1.
Stall speed is totally related to the torque available.

Buy a Yank or similar converter and be done with it.

Ok so im starting to get an idea of what converters to look at. My other question is whats "rolling into the throttle" a friend told me with a converter i would have roll into the throttle before going WOT. Does a converter make the rpms shoot up at part throttle? (sorry for noob question) Btw the car has the 3:15 gear ratio.

It will screw up the drive-ability of the car in traffic. Since you are a noob you have ask an excellent question. Just remember for everything you do there is some kind of a price to pay. Whether its drive-ability reliability or gas mileage everything has a price.
The car in my signature was my DD. I gave up some gas milage for my mods.

To answer the other question - YES it makes the rpm's rise before you feel it pulling but when you reach your stall rpm . . . all hell can break loose if you are not ready (damp/cold road condition, etc..). It will definitely be a [fun] learning curve either way. Your gas millage will probably go down also from being in rpm's more often
I average about 9 - 10 mpg per tank.One more thing, my car is also a daily driver and feel it has ALL of its manners!

My C5 has a 3.42 diff that I swapped in place of the 3.15's and while I was down there I added a Vig. 3400 converter. Had the motor and trans tuned so it drives perfect with great street manners. Its not my DD, but when I cruise it I'm generally out all night and rack up 100 miles or so.... Car shifts like a cadillac. Ditch the runflats and get you a M/T Drag Radial.. 305-35-18 fits great on my car.
