Should I tune with a Gsr or ITR basemap?

My setup consists of:

b18c1 block bored to 81.5mm with usdm itr pistons.
stock gsr head with 00 ITR cams
Performer X Im with ITR TB.
JDM ITR 4-1 header
00 b16 tranny
chipped p06

Im just wondering if it would be better off with the GSR map. My car is currently tuned with an ITR map by me but I was just curious. Im using a lc-1 wideband.

 

anybody? Maybe ill try tuning it with the GSR basemap i made with Crome and see how it runs.

 

gsr is usually the easier map to start out with. so i would say gsr

 

Whys that? I've been tuning my AFR with the ITR basemap with no problems. The only thing im iffy about is the ignition. Which is not possible without a dyno

 

You've got higher compression than a GSR, a manifold that is more similar to an ITR mani than a GSR mani and ITR cams -- start with the ITR map.

 

Yeah thats what I figured. I will be sticking to my ITR map.
