Just got me an early 99 about a year ago. My first diesel. I’ve installed a 4” straight pipe, 6637 wix air filter, pmt1 pcm and a hydra with jelibuilt tunes. Only towed once before the mods and it did pretty well up the 4 lanes heading to shaver lake towing my Jeep. Before I hauled again I got a set of gauges and couldn’t believe how hot I got the EGTs unloaded at WOT. 1300 at about 85mph and it would keep climbing if I didn’t let off. No up pipe leaks, no boost leaks, building about 25lbs of boost. I’ve been doing some research and looks like I’m going to need to get a bigger turbo to get these EGTs to come down. I’ve even tried hydra tunes and they get up to 1300 also. Any other ideas guys? I have a feeling when I go wheeling this weekend I’m gonna have to put it back in stock mode to get up the 4 lane. Please help.
