Heaps Of Mods,but No Power, Why An Plz Help?

The map sensor is what reads intake air temp as well as boost etc as far as I know. So if it read the same on both coolers, it could be a dead sensor. Temp sensors fail all the time.

Thank you so much for that, it is on the to do list for sure.

393whp @ 8psi here. for the love of god get it to a forum sponsor to have a look at. u will wonder y u didnt earlier, too late once it blows remember.

Hi mate, with that tempreture increase would the intercooler be the part that is letting me down from making over320rwkw, I have paid a nice sum for the 1100hp intercooler thinking that it is way enough to handle my goals.

No the intercooler is not your problem, I was simply stating that the intake temperatures you are seeing are normal for a plazmaman cooler.

Take it to someone who has had more experience with the xr6t's (even though you haven't mentioned who your current tuner is) and the sct software instead of throwing new parts at it.

297 rwkw - 03 ba with 130 xxx k's on 15.5 psi ,

20 psi is like doing a 20 dollar hooker bare back

anyways with the 71 degree thermostat my car when driving normal in traffic or even cruising during the day would sit in the areas of 96 to 103 degrees which would be the coolant temps that the tuner would be getting while on the dyno as well, an when my car are at those temps you can actually feel it, its real slugish. I think its to high, so what I did now is change the thermostat to a 82 degree

Correct me if I'm wrong, but changing a 71° thermostat to an 82° means the engine should get hotter faster and stay hotter while driving (assuming airflow is sufficient to lower the coolant temp below rating of thermostat). The thermostat keeps coolant around the engine and bypasses radiator plumbing, until the temp reaches the rating, then it opens to allow coolant from the radiator portion, lowering engine temps. So this will not help lower your temps if they are too high?

My tuner changed the thermostat in mine to a cooler one, now instead of coolant temps being at 1/2 on a normal day, they are just above 1/4. The rest of the tune works fantastic including fuel economy, but I used a very well known shop.

Thanks for your input mate, I know,I just have to take it to someone more experienced, I got a feeling its all in the tune.

Hi mate,yes u are right, but what was happening to me was when I am on a high way cruizing at 80klm an over, the temps would sit at 73 degrees, which is to low I think, but when I was coming up to traffic or stops the temps would go up to 103 degrees. So what I did now is change the thermostat to 82 degree an now it sits perfect on my gauge just above 1/4, an on my obd gauge its sitting on 87 degrees while cruising, I think that's the best temps to be on, but even with my new radiator that I just put on,in traffic im still going up as high as 103 degrees, but now I know why im going up as high as 103 degree its because of what my tuner set the thermo fans to go on at, iv always told him to set it lower an looks like he never done it.

Sounds like a change in workshop is in order. Your Air Intake Temp is interesting. I find that Intake temps generally drop during a WOT run not increase. Cruising IAT should be 130 degrees F and drop to 110 degrees F by mid run for example.

It sound exactly the same as mine!!!

When I put it back to stock and put the standard thermostat back in it ran cooler in traffic than with the 71 degree thermostat. Mine cruising was just under 1/4 but in traffic it would nudge 1/2, which in the end I got the s=%ts with the tune and put it back to stock and sold it. And bought a Fg G6et and its staying stock...
