F1ReB4LL, if you can calculate the last used data sector + add the postgap, you will see that there exactly 151 sectors pregap for "Gale Racer" and 152 sectors pregap for "Gunbird" Track02, and that without any sub analysis !!!
It's wa-ay easier to look into subs than counting all those LBAs.

First of all, you should check the real gap size in the subs (at least, dump the CD with CloneCD and look into its generated .cue). Then, you should look manually at the gap to check, if it's really consist of zeroes. The gap in this case can be not only 00:02:00, it can be 00:01:74, so you shouldn't just always add 2 secs of silence.

I noticed that if we scan the data track with CDmage BEFORE resizing we get the correct amount of sectors to cut.
for this to work the image has to be error free, this worked for me in my Sat and MCD dumps in PSX this usually doesn't work because psxtools needs to fix the damaged sectors.
I'm not saying this is a way to detect the gaps, it's more like a verification Image
