If you could get it to launch you'd be knocking down mid 11s. I'm pretty sure I can do 1.9s with my street tires. How much boost are you launching with?

I have got the car to hook ,but shes a little lazy out of the gate.Track should reopen soon,I have added a little timing on the street ,seat of the pants cant tell,
This is why I wonder about the converter

I'm on my iPad and can't open the log but I'd like to ask what converter and turbo you have now. It's definately lazy off the line.

Looks to me as if the car is pig rich and that will kill the power.  Boost actually came up pretty fast. Voltage is slower than normal.

 its a Edge LU,with a 5857 Ball bearing
I have a TT 6.1 should i lean it out in in low gear

only if you want to try to make it run better.  O2s in low/second should be 760-780 generally...so metimes lower if spraying alky.

I suspect A/F should probably be around 11.1 11.2 in the same gears  Probably 11.0 in third.  Maybe add a degree or two of timing in 1/2

Same rule applies, lean as it will consistently run without any detonation showing up on top end

 So converter looks good its just fat and maybe a voltage is a little low thanks for  your time

voltage probably has no impact on it at the moment...and may never because it depends if the PL voltage reflects actual voltage going to everything or is just what the ecm is converting to from analog to digital

converter looks loose, if anything...but converter quality has a lot to do with performance.  that's the reason serious racers spend a lot more than many of us

Loose on top correct? I have thought it was a little loose on CS in the log and Wallace racing calculator, when I look at the Log I just dont no what im looking at. I'm sure at my power its a OK match
When the track opens ill start leaning it out
