    2015 rxp 260 exhaust temp

    What is the ideal exhaust temp supposed to be on that model?( stock engine so far except cp pistons) i changed the restrictive T fitting on cooling line feeding intercooler with an even size port T and made a separate outlet port dump so there is no more water flow restriction toward intercooler. i am monitoring exhaust temperature with remote probe digital thermometer ziptied on Riva free flow exhaust piping and i can read up to 160F at mid to 3/4 throttle range and temp goes back down to 150F at WOT, gulf temp was at 67F and air at 80. i also slightly enlarged the hole on green reducer between jetpump and transom plate.Is it too cold or good? intercooler is doing his job very well now with more water flow and no more pressure built up as outlet port is wide open, air temp at supercharger outlet 190F, temp just before throttle body is 80.5F, sound very good to me, what do you think?
