Tune eliminates that. On a private testing area, the needle's been past the end of the numbers.BTW top speed is 107 mph from factory. IDK if 5* raises speed limiter. I assume they do.
The E30 5 Star tune is flat-out incredible. Throttle response even low-down is super quick, and the top end is amazing. About the only downside I see is that since it's an overall performance tune, it eliminates the skip-shift at light throttle, which the 87 Perf/Tow tune retains. The additional torque actually makes the skip-shift fun, since the large RPM drop keeps bringing you back to where the torque peaks.
Considering that if you want to mix your own 30% E85/gas blend, you can pick up an additional 50-60rwhp over 93 octane (5 Star has some dyno graphs of 100% stock trucks on E30 tune @ 500RWHP!) and not have to change anything else on the truck, I think it's an amazing investment for $170 over a basic BDX tuner. I do think that on the dragstrip though, with this tune, I would definitely benefit from an upgraded intercooler to help with heat soak. Anybody already upgraded their intercooler on their 3.5 EB?
