Thanks for the feedback guys. Im located in Fiji and there are no dynos here thats why im looking at using the factory ecu. I have everything else sorted out but still deciding on the turbo setup as i would like to run high to mid 12's down the quarter.

I guess one option would be to find someone sr20 ute who is running 12's, copy the same setup including ecu and see how i go. Im only worried about the climate here as max temps are only 34/35 deg cel but its really humid. Wonder if that will have a drastic effect on the tune.

Anyone running an sr20det and has done low 12's...lol

Thanks again guys. Really appreciate it. Will post some pics of the ute soon.
