When your comparing your dyno numbers to the track are you using corrected numbers that most dynos produce.
You have think weight is not everything. If you are comparing to a stock truck as in height wheels and tires can cause time also. Skinny tires on my car were a few tenths compared to the normal wheel and tires. Not worth it for me so I didn't run them because the car squirmed at the big end. For me 1/8 mile is hard to tell HP problems because you don't the the time and MPH difference between 1/8 and 1/4. But both having a 71 big turbo shouldn't that mean the HP is about the same. Seems like you have a lot of fuel for those chargers.

I do agree it's too much fuel for those little drop-ins. I wouldn't run such a high PW tune if it didn't make more power.
I have a set of platinum 20s with Michelin I've tired aswell. I gained 0.10 MPH on my trap speed swapping them out. I also agree it's tough to judge of a eighth mile time. I think I'll try to find a close 1/4 soon so I can see the full picture.
Since I've been around 6.4s I've always herd you need a gate if you spray, or add fuel. So why can't I exceed 68 even with the gate fully closed?
