A few months ago, I installed an isspro pyrometer Pre turbo. I was shocked to see that with my milage miser 50hp chip I was reaching up to 1500 degrees pulling hills at full throttle empty. I took out the chip, and it only made about a 100 degree difference. towing my toy hauler without the chip I can reach 1400 pretty easily pulling hills. Half the people I ask, say this is normal for an 05, and the other half say I should never be over 1100-1200. any suggestions?
