Most including myself start at like 40-50 and go WOT in the highest RPM and lowest gear possible. You can start at 0 if you like, but the point is to get the lowest time from 60-130, so starting at 60 and dropping a gear would only kill the time.

I've hit 11.7X to 11.9X with both tunes on various days and nights in hot & cool weather DA and temps. Overall I'm happy with Loi's tune as of now and just waiting on him to finish the E85 NA ISF tune which is the one I really want to run and do testing on.
Pretty sure I just watched a video of your car on Instagram shifting at 7500 rpm (tach view). The torque converter sure looked locked to me. I’m not brave like you in revving that high, but happy to see the fast and smooth shifts at that rpm. I was surprised to see it continuing to pull just as hard at that RPM as well. It doesn’t look like power falls off at all.

Yeah that's my cluster video. That video was done at night on a incline canyon road and is bumpy at some spots.

We went to Sacramento this past Sunday. Great day on getting consistent 11.8 ET and 119mph trap speeds throughout the day as it got hotter. I'll be uploading a few more cluster videos tomorrow showing 1st to 6th WOT gear shifts.

Transmission tune looks solid with your shorter gears!

Thanks to this thread, I’m gonna try Loi’s tune on my 11. I’ll leave RR tune on my 08 for comparison.

His tune intrigues me with the transmission and fulll E-85 tune in the works, but the CEL would drive me bonkers since I've been use to no CEL with RR tune going on 6 years this July. I really hope Loi incorporates the elimination of the CEL to avoid having to go the simulator route. I've seen way too many wiring issues with people who have had simulators and I don't want to deal with it honestly.

This is purely a SOFTWARE limitation. Not, Tuner.

VF is set to release v1.60 at the end of the month, with this being one of many added features.

The eliminators aren’t wired anymore. PPE made some elbow extensions that go directly in the exhaust to fix it.


I’m currently fixing wiring issues from the old garbage style. Definitely don’t use anything requiring wire modifications.

For whatever reason, PPE stop making and or selling the 90 degree defouler. But, they provided me a link from eBay to purchase a set. My first set of headers came with the defouler and my second set didn’t. Hence how I got the link.

They stopped selling them due to EPA enforcement, unfortunately. But they did suggest the 90 degree defouler as a solution.

Now I want to hear your launch procedure. I thought the fastest way down a strip was to roll off the line, but your stalling at 1500 rpm. Have you found more speed doing that? Is that tune related?

That's encouraging to hear!! I might make the switch over if that's the case😎.....going to run FilwithanF here soon to have an idea on how the 2 tunes compare to each other, based on that I'll make my decision.

See if you can make it as fair as possible. Example - both have full tanks; not a bunch of luggage or passengers, etc.
