Results of pre-turbo meth injection

[Killa_dsm]

Well with the great results I was having with meth injection at the throttle body with a m14 nozzle I decided to add a m3 pre-turbo nozzle as well. After reading a thread written by turboglenn I decided to try it myself. Here are 2 logs of 3rd gear pulls without and with the pre-turbo meth injection. No changes were done to my tune or my boost level when doing both these logs. I really didn't feel an increase in spool nor any power difference between the two logs. I am sure I will see better results with some more fine tunning or upping the boost.

The boost level in which the meth kicks on is set to around 13psi. I set it low because I was having issues with the meth not coming on fast enough in 1st and 2nd gear pulls since boost shoots up really quick in those gears. At this point if I go into boost at part throttle in 5th or even 4th I get bogging issues once the meth kicks on. Now I wish I would have got the devils-own progressive kit instead of the normal one I have. I will be playing with activating the meth at a higher boost level to try and get rid of this bogging issue. But the bogging doesnt happen in wot pulls which is good.

And also I dont think my Greddy Type-S is able to hold those boost levels, because during those pulls I could hear the bov fluttering.

Let me know what you guys think.
