It's like I have to go fast from a dead stop to clear up the valve noise. Is this normal? Maybe I can hear more engine noise since the exhaust is free flow?
I'm like the my no DPF truck, but I'm not too impressed with the tuner. I rode in my buddies truck that has a SCT and I was much more impressed with the quality.
Any help with my questions would be greatly appreciated.
Are you running the tunes that came with the Mini Maxx. I noticed what i would call Timing noise after downloading the Hot Damn tune, dont remember hearing it with the original tune.
For shifting try downloading another tune off the website, i like the 45 mph lockup the best, mine wont lock until about 52 which is where i want it. Also try downloading to stock and then re-downloading and do your tranny relearn in mild instead of hot.
They also have some "Easy Tunes" on their website that you can try.
I have noticed the longer i leave mine on a tune the better it shifts, i have also played around with acceleration and found out that you can make it shift better by going a little harder or a little slower than where you normally would accelerate
