I've been noticing a lot of TruControl and Hotbox owners who complain about issues with the engine performance and health on the FB forums. I think I know why this is happening.
Z1 and Stillen should've explained that in order to get great CONSISTENT performance from these units you NEED to have an upgraded Heat Exchanger!!
There's a reason I don't run Map7 on my car but now that I have the CZP Heat Exchanger I will give it a try. It works amazing with the mid maps(4/5) with the upgraded h/x in very humid 90+ degree F temps in Georgia.
And most of the people complaining of issues are those with the stock h/x during summer time horrific temperatures.
So to those that don't have issues what Map are you using? Do you have a upgraded h/x?
