I believe the intake temp thermometer was placed in the line that used to connect to my blow off valve (run overboost valve now) or some line that looked very similar. I will clarify when I pick up the vehicle Link to comment Share on other sites More sharing options...

I've posted both my original e85 tune at 21psi and my new one at 20psi (changes include second 044 pump and overboost issues sorted by replacing cracked exhaust housing). Between the tune conducted this time last year and the current tune its picked up in about 100nm of torque and between 30-45rwkw across the mid range. top end power only increased by 14rwkw though this is with 1psi less boost.Biggest change has been driving experience, boost comes on so Fcuking hard that it makes me feel ill... I love it but need a lot softer tune for daily duties as I cant see the gearbox surviving the weekend. Drags are on next time im home from work so will see if I cant run that 10 second pass on my sh*tty $159 tyres, this will hopefully shed some more light on how well the new cooler is performing Will have more data as soon as my tuner emails it to me.Cheers,Jarrad 2 Link to comment Share on other sites More sharing options...

arronm Dropping a turd Gold Donating Members 9,520 Member For: 17y 1m 17d Gender: Male Location: Perth Posted 26/09/14 12:38 PM Share Posted 26/09/14 12:38 PM The boost is just commanded earlier in the second tune. Not much dif in total power. In the latest tune power between 4000-5000 is up 10kw but between 5000-5600 its flat when compared with the old tune. 1 Link to comment Share on other sites More sharing options...
