Some of you have been following my posts lately about truck problems and it doesn't seem to end with this truck for some reason. Well today was borderline disaster. I got my dyno spot for this event about a month ago and it feels like I've been getting ready for "the big day" ever since. The truck has constantly been in the shop, putting a couple hundred into every week it seems and it still isn't right.
I was planning on using my new tune from Tony Wildman today but I learned on the ride there that the rev limiter wasn't removed. I maxed out at 95mph on the turnpike and lost to a Cummins racing. I loaded a revised tune from Vivian for the 175'75's and the trans would not cooperate. Slamming itself into second gear repeatedly and missing shifts. I put my old SPD tune on that was written for my 155/30's.
The whole ride the my truck was puking coolant. It hasn't puked since my last stud job 8 months ago! I just put a brand new NAPA bottle on the truck and the cap litteraly blew off and was laying in my engine bay, Coolant everywhere, white smoke everywhere like I did a huge burnout. I had to stop at the auto parts store and get more coolant. Mixing green with my red because I lost alot. I had an extra cap in the truck and I puked with that one too. I borrowed a cap from a friend at the truck show and made a test run, puked a tiny bit but not like before. The truck only puked at 35psi and once it did the needle went all over the place.
I broke my 500rwhp goal so I'm happy and smokeless to boot! But now I have to find out what wrong with this truck. Happy and nervous, I hope its just a cap...
