Jestr M1 flash gained me 20whp/50ft-lbs
This is my experience with my Jestr Mode M1 Flash.
I shot Jestr an email with my stock Evo IX rom, and gave him a list of mods, and
what octane i'm running. Paypalled him, and He emailed me my baseflash. Very straight forward transaction that took less than 16 hours.
So I had some time today to do bunch of logging runs to get the before and after
affects of the flash, and boost pill removal. Lets just say i'm pretty pleased with
the results. I still need to do more logging because every now and then i seem to
get a little knock in the upper rpms past 6k, but most logs show very minimal knock sums, and usually the pulls have 0 all the way through.
My only real power mod was a TurboXS Catback.
For reference heres a screenshot of some dyno pulls taken at swift motorsports in
CT. They run a dyno dynamics with inflated numbers to very closely match dynojet
numbers. It was 70* that day, and i believe the pull was done in 4th gear.
it shows 270whp/250wtq
Heres a typical powergraph generated in DLL. it was around 50* and all pulls were made in 3rd. I did about 4 pulls that average out to 280whp/248tq
Heres a typical run after the flash, with stock boost.
And heres what i logged after removing the recommended restrictor pill.
averaging roughly 300whp/300tq !!!
So my logs show a peak gain of 20whp and a peak gain of 50ft/lbs!!!!
Stock boost used to spike to 20psi bounce around, and then taper to 16psi. The flash took care of the taper, and the bouncing, and removing the restrictor pill bumped the spike to ~23/24psi and holds pretty solid at 19psi to redline. Not only that but the stock tune was a little rough, and this flash definately smoothed things out.
Hope this helps anyone out considering a jestr M1 flash.

Not bad but the boost alone would give you most of that power and torque but off course the boost is complemented by the tune and viceversa.
Your boost was altered significantly, I honestly would expected perhaps even more whp but that 20whp/50lbtq is not a bad deal at all.

First, start the car when cold in the morning, then drive it for 10 minutes. My logging site is 10 minutes away from my house so the car is warm by then. I usually keep the coolant temp @ 182-185 F and the air temp @ 75-80 F when logging.
Second, do 3-4 logs @ the same time @ the same place. The first log is usually the one that you will not use. The results of the last three should tell you if there is knock or not.
Third, try to log during the same time of the day. Next to where I log there is a weather station and I get to check the temp, pressure, and humidity before I go logging. I have found that humidity (I am @ seas level 15 minutes from the ocean), kills my boost. Humidity of 70% and above lowers my boost by about 1.5 psi.
Please post your logs afterwards.

heres the last 4 logs showing knock and timing.
the spot is 20 minutes from my house. its pretty flat but i logged pulls going both directions. Coolant 182-184* AirTemp was 70 and would gradually drop to 47 during WOT.
first logs were done at 8pm, last ones were done at 913

You should get an AFR meter so you can figure out your AFR ratio.
