What's your 2-step at, and how much boost do you build?
Just wanted to see what other peoples settings where. I just installed the PEMS on the SRT and wondering how much boost your seeing at launch..
These are my mods
Engine: JE pistons, Eagle Rods (stock CR)
Valve Train: Crane (Crane 14)
Turbo (47LB E3) Going with a 65mm turbo or larger soon
Boost: 3-4 psig
Fuel Cut: 4400
Ign Cut: 4400
Retard Rev: 4400
I like lauching at that RPM mainly because of the short gearing in 1rst on the T850 trans.. When I raise it to 5300 (2 step) I build maybe 9 psi.. Is there anyway to get 9-10 psi at only 4300 rpms? I can always do anti- lag but dont want to go that route as yet haha

there is the drag anti-lag that will help you build boost just dont use the rally anti lag
The purpose of ignition advance is to account for the lag time following spark ignition for combustion pressure to peak at 15 degrees AFTER TOP DEAD CENTER. A little fyi !
Haha my best pals here has a mitsubishi with a precision 62mm turbo charger that uses Antilag and builds 20+ psi in like 2 seconds Lol. He gets his Aem tuned by Turbotrix in Jersey blah, blah but this thread is not about antilag.. Hopefully someone can answer my original question about building more than 5 psi at around 4500 rpms bump!

sorry dude its 100% dependent on the amount of exhaust gas, and at 4500 5 psi is about all your gonna get (it will varry a great deal from build to build), using anti lag is a great option to build boost on the line, you could do a poor man anti lag and retard the ignition and add fuel in the area where you 2step it but this will kill your drivability
anti lag is only extra fuel and a very retarded ignition, this will will allow the A/F mix to expand in the exhaust manifold and not the combustion chamber and yes it will make you spool very fast but the motor will not have power untill you come out of anti lag and by that time there is a ton of inirtial energy built up, i played with it for a while and 20psi is easy to build but will eat a motor (valves and turbine) in a couple seconds, while using the rally anti lag (do not try this) my car would hit 20+ at 2k rpm but would take till 2500 to make power (ecu returns timing and lowers fuel) with out it i would spool 20 at around 3300 (800 rpm added to power band)
its how you use the timing and fueling, if you want drop the timing 2-3* and add about 10% fuel in the area where you are trying to build boost. just remember to smooth out the map when your done
not sure of what your question was but i hope this helps a bit
hint: i would use a switch and drag anti lag as to not fuk up your maps
