when ya dynoing?
Thanks for the tips guys it will come in handy, seems like eveyone is still new to this.
That's why i contacted devilsown if anyone would know it would be them that's why they sell the kit.

I made my "Meth Purge" system, and I notice sometimes that when I do purge (for a split second), it doesnt affect the A/F because the meth in the lines AFTER the CV is gone and has to refill again. 2nd push of the purge DOES work since the lines are filled again.
I think with a 50 trim, 1 M5 and 1 M3 or just 1 M7 before the sensor.
I talked to devilsown for about 30min on the phone and the M# break down Is like this.
M3= 3 gallons an hour
M5= 5 gallons an hour
M7= 7 gallons an hour
And so on you shoud get the picture the bigger the number the more it flows an hour. He said with just 1 m5 that is alot right there but it shouldn't be too much and he said the best way to find out if you need more or less is to monitor your Iat (Intake Air Temps) temps if the temps are close or over 98* you need bigger.
And that's why we decided to go with one M5 and it will be closest to the Intercooler right after the 90* bend on the uhp on the back side of it.
Located on the trany side firing @ the I/c.
We are going to dyno Tuesday this week on 100% 91 pump gas then race gas. So he can see the improvement of the Ed super beast Bfmic & Dcr oil mod over his last dyno.
50 trim@19psi 100% 91 pump gas with the turbo xs Bfmic it was heat soaked after one run and lost 20hp. It could barley hold power after one gear on the dyno.
So he wants to see what it puts down on 100% 91pump gas with the new mods over the old ones above^. And how much he can get out of it
before the meth kit goes on.
Then we will put the meth kit on and see where that takes him we still have to order the parts so it will be like middle of Aug. when we put it on street tune it and throw it on the dyno.
