it makes a big diff what actuater you run, take it off and have a look, are you running with or with out the amal valve? and do you no what boost your running?
- 31 starts at about 7 psi and gives a nice smooth power curve, -34 starts at 14 psi and comes in late with a big bang hence the -34 will kick in later in the revs, and the piper cam will only kick in late about 4 rpm.. you need to learn all of the above to start to understand whats going on mate biger turbo means more lag and small turbo means hardly any lag, as t2 is boosting at 2rpm and t3 starts at 3/3 and a half and so on, then you get to t4 = big lag
