If its a healthy pump leave it be. More fuel equals faster boom...

Bag O Parts is a scam, lbz fpr will raise fuel pressure but probably not worth the money or effort in the end. I would raise your shift points a few hundred turns to keep that 68mm in its happy zone and go have fun with it untill you get numb to the power and you need more...:D


How exactly can i change the shift points to keep it in the happy zone? V2? And the al5 controller? All i have is ecm tunes emailed with an autocal. Truck seems a tad bit sluggish especially off the get go, then builds boost fast and hard, then falls off at the top, probably because of the fuel flow lacking.

Need to get your tuner to send you some TCM tuning.
