So I now have the "TuneECU" & I have 3 maps downloaded, the one I need to use is 20219 which is for TORS exhausts with cat box removed but what is the difference between this & TORS with no cat ?. I guess at this point I need to buy the cable to connect my PC to the ECU & is it then a simple task of selecting the required map & letting the programme do it's thing or do I need a crash degree course in engine tuning. BTW does this map (20219) stop the decel popping?. WOW am I in too deep hear? feel like I'm drowning, about to make a major F**** up & have to call in the Triumph guys.
