Engine/Transmission (1998.5 - 2002) Fueling Box ?'s

[78repowerwagon]

I do not have dyno numbers to back that up if thats what you mean. Looking at their claimed power ratings all three boxes make about the same level of power(120-130hp max gain). Some make more down low, the comp has timing added in, and some make more top end power (FMS). Add the timing to a TST or FMS and you will make more power everywhere. Plus the TST competition version makes ?140? alone without timing.



I would like to see dyno graphs comparing all three boxes with stock injectors for a baseline and them large (like 8's) for comparison at both ends of the scale, same truck, same dyno, same day.



I am not interested in peak gains, but across the graph, how does it do. I have an ATV dyno and can build a motor to make very impressive peak power, but it has to carry decent power for several thousand Rpms or it is unrideable.

I made the power in my sig with the stacked boxes. It's not a direct comparison (different days, different dynos), but I know a guy who made just 450 hp with a comp (drag I think) and the same injectors. I was also fighting the 0 fuel pressure issue at the time of the dyno, so I suspect I would be even higher with a better lift pump. I plan to redyno soon.



78re... I'd love to use that dyno of yours for my race bikes. I have a good guess at to what they would make, but I'd like to see 'em on the rollers.
