been running this setup for awhile now and thinking about what to do next. iv been thinking about a diff cam but every time i think im set on one i read something that changes my mind. i know my tires are killing me being 275/55/20. other than that what would be a good next step for a daily driver mods are-
212/218 low lift
circle d2800
PB lvl2
trutrac with 3.73

 

good shot of nitrous, just sayin...........................

 

Tbss intake and ls3 throttle body. Would pull hard on top with a tsp220 cam which would work nicely with your circle-d imo.

 

The top end would be pretty decent with a tsp220, I agree. Either that or get a custom grind from EPS like everybody and their momma is getting nowadays.

I have pretty good top end on the interstate with the ole tsp220, some people tell me my truck looks like a "grandpa's truck" but sounds badass when they hear it running, or when they see me pass by them on the interstate occasionally doing 120-130 they are like wtf bc it looks stock lol.

 

how does the tr220 compare to the tsp220, i know one is .551 and i believe the other is .581 but how do they compare in performance

 

Don't think you can go wrong with either, they are about the same in comparison to performance really. There is a thread on this about the two somewhere on here if you search where TSP techs chime in.

To sum it up quickly I think the TR powerband comes in a tad sooner and the TSP has a little more Top end with the higher lift. Find and read the thread though when you find it.

 

i did actually see it after posting, what injectors are you guys running with these cams? im at 94% duty cycle now so im sure some 8.1 injectors will be needed

 

You won't need to get bigger injectors if you are at 94% and you already have all the bolt-ons installed. All you are doing is swapping one cam for one slightly bigger so you will def be fine. Now if you already had 94% dc without some of your bolt-ons then I could see changing them out.

Up to you if you want to go ahead and upgrade the injectors, do you have any plans on going FI or adding heads down the road? If so I would go ahead and upgrade then, if not stick with the stockers.

 

no plans to go FI or add heads.
got some pac 1218 springs so now i guess its which one i find for a better deal

 

FYI; with just the tr220 cam, longtube headers and ORY and CAI I had to change injectors because the stock ones were maxed out.
