I have the same tire size and gearing. I also have absolutely no power. If it is windy top speed is about 50. Did you also replace the TB with 4.0 TB?? Has it helped with power issues??

My top speed with a head wind is also 50-55. I do have a 4.0TB, but I havent put it on yet.Just trying 1 thing at a time to see what the difference is. I did grind out the intake bigger before I installed the TB spacer.

That is enough tire to change the shift point on the automatic transmission. You need to change the speedo gears for correct shifting.
