Way Hot!!
With just a stock hx-35 I didn't have temp problems until atleast level 3. And in level 3 you would have to be going from a stop to triple digit speeds at WOT. Now I can run in level 4 before I have anything close to high temps but it still takes a while at WOT. Level 5 Gets hot in a Hurry. You're runnig a PDR-35 and shoul be in pretty good shape.
Do you have guages? If so what kind of boost are you running. With no leaks you would be pushing high 30s on your boost with the comp in any of the higher settings. Check all your intercooler boots and clamps. Try running down the road with the Comp off (Injectors Only) give us the boost number, then comp on level 1, level 2, level 3, level 4, level 5. Then report back with the peak boost numbers you recieved in each of the settings.
