2 step question
Typically you would advance timing on a stick to build boost on a 2 step and retard it with an auto. I target the same AFR regardless of 11.5-11.9:1 and dont mess with timing yet.
INCORRECT. You RETARD timing with a manual and ADVANCE timing with an auto. Retarding timing on the stick helps cause unburnt fuel to spool the turbo off the line.
Are you using like a LPE 2 step for example? most try the 2 step out with no timing retarded and see how well it works then slowly retard more and more timing until the desired result is achieved.

Thanks for all the feedback (no sarcasm intended) but does anyone have an answer to the two original questions?
For a Manual Car:
1. What do you retard the timing too with the 2 step engaged (or what have you found to work well)?
2. What AFR do you target with the 2 step engaged (is approximately 11.5:1 what others target)?

for the AFR i would not worry about it because its going to go rich as hell do to the spark being cut out
but you need to start low and work your way up and see what works best for you man go have fun with it thats my 2cents
Mine makes about 7 psi at 4K RPM with the base 13* that I am running. I 60' in the low to mid 1.4's. I tuned the car to run 11.5 target and have it setup to error towards the 11.9 mark. I did no special tuning specific to the 2 step.
So you only run 13* of timing? Just wondering, I'm running 17 18*.
Yeah, I run a RMVB TH350 with tbrake and about a 4500 stall from FTI. It currently has a 3.73 gear but due to the lowering of my rev limiter to 6500, I'm out of gear by about the 1200'-1250' mark. I have done pretty much all the suspension mods. The chassis had a 408ci + 380 shot and has been 9.33 @ 146. I didn't (still don't) have the money to forge the bottom end and throw my heads on it after blowing up my old setup. I decided to throw in a cheap stock iron LQ9 long block and get the turbo kit all fabbed up so I could get back on the road.
As far as timing is concerned, I figured that it might last a little longer at 13* seeing as though I am hitting it with 15-16#'s on 93 octane.
