Here is a short vid of my dyno tuning session today.

Final dynojet numbers were: 327hp 317tq 2nd gear unlocked
Truck was pretty heat soaked and temp in the bay was around 90deg.

I am happy truck feels alot better. Waiting on the graphs to get emailed to me, will post them asap.

Cam specs. Comp Xer Lobes 222/222 .568/.568 114lsa

The sheets are going to be emailed to me this weekend.

My injectors were maxed at 112% duty cycle at 6000 rpm so looking for some bigger injectors now.

Dyno operator wouldnt let my tuner do a 3rd gear unlocked pull otherwise the numbers would be alot better. But then again its just numbers, the trucks awesome now.

Got the email with the dyno sheet. All runs were done uncorrected and in 2nd gear unlocked, reason the numbers are low it was close to 90deg in the bay and my truck was pretty heat soaked on the final pull. Had to let off at around 6k because injectors were maxxed out. Im looking for some 8.1l injectors and we are going to try again.

Thanks! Truck feel Alot better and more responsive. He ended up adding 4 degrees of timing bumping it to 28* total on 92 octane.

Very happy so far with his tune, hopefully we can find some more ponies with new injectors.
