Thread: Calum or Haltech?

honestly i dont think that a stand alone is really a overkill for even 200whp, if you want other options like, gear dependent boost control, electronic boost control,abs traction control,2 step launch control,variable knock sensor,MAP,nitrous control,ect, and have all the ability to control basicly every aspect of your engine and tune to the full capability.

personally i am having my car retuned and i have the aem ems, and im getting the gm boost solenoid installed and having my boost maps tweaked and recalibrated and the tuner said he sees a average of 300-500rpm in spool increase, so really the variables of fll stand alone are always a plus at any power level, it just depends on how much money you are actually looking to spend, or how serious this setup really is.

GM Boost solenoid for the loss. It is loud, isn't very accurate and can't do more than 15psi with any reliability. Get a greddy or equivalent boost control valve.

Again, if you only want to run larger injectors and maf and want to do basic A/F changes hen get the Calum. It will give you every ability to do all of that!

Before you go saying that the tune is that lean what was your timing set at? Most likely you had it way too advanced and calum's ecu loves to push lots of timing.

timing's at 15 there hank. and the dyno told me it was too lean before i went saying anything.

true

Standalones are so overrated.

Fuel pressure, stock fuel pump, etc. So many factors that could have caused that besides the ecu. Nevertheless, we must leave room for error because it happens.
