Default Difference between -31 and -34

You can fine tune one of them more than the other

Well Graceland i presume a -31 is better as thats what i been told to get But just wondering where a -34 would be better as obviously there must have been a need to produce it?

Base lift pressure is alot higher on the -34 (14psi compared to 7psi from memory, which could be wrong)

You're T34, greys & 30psi aren't you Rhys?

I was told -34 is worthwhile on anything stage 3 or over

GurnE supposed to be running over 30psi but currently car is only going to 25

Well Mark said -31 even for the boost so im getting one of those, as he knows what to do with the engine. Maybe its down as said above u can fine tune it more?

Just to contradict Dingly, go for the -31, as combined with the correct jets in the amal valve and boost map in the chip, it does exactly what you want it to . Just listen to your tuner .

Well, I'd always say follow the advice of your tuner.

I went from a -31 to a -34 but also went to greys,T34 and boost controller all @ the same time so couldn't tell you if the actuator alone made any difference

i have - 34 as recomended by stu but dont forget guys the main diff is lift off -34 needs 14 psi before lift will start and kicks you in the backside.. - 31 lifts at 7 and does the job smoothly dont also forget .. no amal valve means -34 with amal valve its up to you..

andzz
