I already bought my Mach 5's last month since they were on sale
But I wont be getting my B1 until next month. Its really hard looking at these Mach 5's everyday imagineing all of my future power. Would it be safe if I put them in until I got my full B1. I would keep a watchful eye on my EGT gauge of course and I wont be towing either. Maybe a few WOT spurts but thats it.
I know what I should do but its getting harder everyday.
Thanks
