How is the stall doing on the street? Does it free-wheel when you let off the gas like some of them do? The one Greg is doing for me is (PTGM255HS) which cost a little more but stalls to 2800 to 3000 so I can hit the nitrous soon as I leave the line. I should get some killer 60ft. times with Nitto DR's I have 305-45-18". I am running two stage either 50 HP & 75 hp or 75 hp & 75 hp with a 2.5 second delay for stage two. Thanks

Mine is all back together and the transmission and torque converter ROCK. I sware it feel like I picked another 50 RWHP from everything I just finished. This TBSS is flat out fast compared to before!!!!

I dont have a problem letting you see how it does so long as I can get everything finished by the time you get here. I spent the whole day today at the Exhaust Shop. Tmorrow I will be putting the Hughes Deep transmission pan on. I also need to add the Boost Gauge and take some datalogs to compare to the smaller pulley.

i have been debating cam or tranny work as next mod and I am beginning to lean toward the TC and some minor tranny work.

Would you suggest different? I only have CAI, MAF, UDP, EFans, Tune from ADM

What has the torque converter done to your daily driving? What are you tacking say going 65 MPH?
Under light throttle the torque converter is real nice and isn't that noticeable. Under Wide Open Throttle it revs faster and throws you into the seat real good. I need to lower my shift speeds a little because I am hitting the rev limiter in 2nd gear right now. There is a little difference during WOT and the speeds unless it is locked up. I don't see the speed in OD vs RPM changing because of the lock up.

In open loop, how have you addressed the "aggressive" CMD AFR when the converter is locked up? For instance.. converter locks up.. you are in 4th on the highway.. You want to keep it locked and accelerate from 55 to 65.. OL commands a stupid rich AFR.. Especially with the AC on.. I have dialed down the OL vs IVT tables some but I am wondering what the limits are for a/f under high load, low(ish) rpm. CL used to command 14.7 until it entered PE mode. Is this type of afr 'scheme' acceptable for a N/A car?

You should not keep it locked from 55-65 mph on the highway. Mine is set to unlock with any increase in TPS% then to downshift with a little more. You dont want to lug it so bad on the highway that is what is happeneing to your AFR. The commanded AFR tables should be left alone and if you have an '06 you can change the VE tables to correct your LT and ST Fuel Trims.
