wait. So it’s not running well? This was me cruising in 4th with the converter locked. I matter it, the converter had to unlock, and it had to drop a gear. Doing all that I thought it spooled pretty quick. It spools twice as fast if I’m in second gear and stab it. I have stock heads cam and headers so maybe that’s the restriction you’re speaking of. This turbo is rated at 675 crank HP
