hi guys i posted a ? about installing your inner cooler on a 04 gtx. thanks got your anser, will iam not to swift, but , if the computer can adjust for extrem cold air like 20--or 30 degres temp, or colder. could it ajust with your inner cooler installed, say 60-70-80 degrese ambent airtemp.actully, i was hoping the only difrance between the 185hp. and 215hp. was the inner cooler, my wife will be if i till her i have to dump the 185 fou a 215hp. just so i can mod it up.she says, iam a hp. junkie, and need couseling for moter mainuia, please send good cousel

It isn't just the increase/decrease in temp that is an issue. Our Stage II Kits significatnly increase boost which requires more fuel. So far we have determined that the 185hp non-Intercooled engine ECU's cannot provide the additional fuel.

The other issue is the 185hp engines do not use forged pistons. Our Stage II Kits increase compression. That is the other reason we do not recommend them for the 185hp non-Intercooled 4-TEC engines. (I posted this info in my other reply!)
