Mbud, yea i could get the smoke if i want but like i said the guy working on my truck got the tunes for me and i know he had the fuel pulled back at least on the street tune and tow tune. Havent had a chance to try the race tune but will be some time. I plan on getting Matt at gearhead to tune it some time but want to get the fuel thing we have talked about worked out. And honestly the truck is fast enough.

 

Agreed, and I think I understand that you're planning on upgrading further down the road, thus the reason for even getting the 155's in the first place. I just see guys who think they want/need bigger injectors, but don't plan on upgrading air... well what's the point then? Stick with the sufficient stock injectors!
