FYI, a guy local to me just got his 135i protuned for E50 and put down 421 whp / 505 TQ on a Mustang Dyno. Those are some serious numbers!!

Those were taken directly from the dyno sheet. I just noticed that it was a 1M though.

It being a 1M shouldn't make any difference.

The 1M is rated at 340 hp from the factory.

Yes, from the OEM DME tuning's Overboost function

Gotcha. So other than the factory tune, the n54 hardware is the same?

As far as I know, the N54is that is in the 1M and the 335is has an upgraded cooling fan, and the overboost function which allows for hitting 11psi in the mid range for a few seconds then tapers off

Well that's encouraging. I am going to the same shop for my protune and was planning on getting tuned for 40% E85. Might want to bump it up to 50%.

Based on your log i would suggest replacing your Low pressure fuel pump before you go for big numbers on a high ethanol %. Its having trouble keeping up already.

I am going to log a few more times to see if the LPFP is still acting up. I just haven't had a chance this week.

Pretty happy with this E30 tune. Running 50/50 E85 & CALI 91 Octane. Data logs will be posted later.

I will be running the race gas map at the drag strip tonight for the first time (I will have at least 100oct in there). I have all the necessary supporting mods (HPF FMIC, AR Catless DPs, Intake).
From the directions, it looks like the only thing on the race gas map I need to keep an eye on is the timing drops. Since I will not be able to review my logs until I get home after the session, is there anything in particular I should be monitoring during the runs to make sure the map is not too aggressive for me, especially at 5800' altitude?

Ran at the dragstrip tonight with the race map, (2 gal of 91 octane blended with 6 gal. of 104 octane). Pulled a log of my best run, 12.88s @ 110mph, which is pretty good for my altitude and a DA of 6530 ft. I think it looks pretty good overall. What do you all think?

Am I reading it right that you had several 6.x degree timing pulls and one 10+ degree timing pull? If so I'd say you needed straight race gas or a little less aggressive timing. I know I pulled a bit here and there on the E30 map, which I think is the same timing map.
