Dude, your EGT gauge must be broken. lol. How are you only seeing 1550º with a VVT and 80% sticks? I dont think you are pushing it hard enough. :D I can get my S475 to 1500º at WOT on the highway once it shifts into 6th. That's on a 2400µs pulse and 30º with 40s and a single stock pump.


That's what everyone keeps saying. Lol. It's not broken though, It just never gets that hot. My biggest tune is 2450us and the highest temp I have ever seen it was 1650 when it was like 98* the other day and on the biggest tune at like 120mph+.

Tune big injectors?

0-80mm3=stock
80+mm3= all red everything

At least that's how they do it on the craigs list :D

try making your US closer to the same not a couple hundred US different, use the scan tool to watch the blue box in the cells and see which ones it is using to see if that can help smooth it out. might even try setting the pulse the same in the MAin Injection table where it is iding. My thought is with the bigger injectors that couple hundred US can have an effect on the idle and it is trying to keep the idle the same and it is going back and forath. I have found this to help in my experience.
