The tune
will not change the throttle lag in a NA, I cant say for sure about the SRT but I know several guys with SRT's that did buy a SB. I have both a SB and eurocharged tune and will say this, if throttle lag bothers you I would install a SB first, I promise you will never regret it.... then I would quickly get a ECU tune and you will be just thrilled!
So to me,
1.Install a Sprint Booster
2.Get a Eurocharged ECU tune.
3.JMHO
