Default new here with my lifted 07

ive been around here for a while reading up on stuff. i have a 2007 silverado ecsb 4x4 with a 6 inch BDS lift on 35/12.5/18s and XD diesels.

i have the GMPP CAI, MBRP dual exhaust, and BlackBearPerformance tune. Really soon i will be getting 4.56 or maybe 4.88(for more performance) motive gears, maybe a true trac with a mag-hytec rear diff cover and maybe switching out for a smaller spacer in the front to reduce the axle angles, as well as a retune from BBP in november.

Hopefully by next year I will do some colormatching and cosmetic stuff. I am hoping to get some LPP LT’s, and if enough money I might go as far as a cam(gotta do a lot of research for this), and changing the exhaust routing a bit with some high flow cats, cutout, powdercoated black with side exit flush with the bottom of the fenders. Just cant find a single in/out MBRP muffler that’s not diesel or a dual in/out. also might put a s/c on it a few years down the road, so that would effect the cam i would put into it for it being boost capable.

if theres any good threads to read up on i coulda missed on the gmt900 cam swaps, what type of cams, stalls, trans upgrades, etc. post up info or stuff here i have until probably next spring before i get to tear into this thing again.

heres a couple pics of the truck:

man your truck looks great... and your definately on the right track as far as what you have in mind for upgrades. 4.56 gears is what would be called for 35" tires, not too sure about going to 4.88's

I have a 3k stall Circle D and I absolutely love it. Great boost to launch out of. Also go with the Oregon Performance trucool 40k gvwr trans cooler when you do get the torque converter. the TQ converter will increase trans temps substantially.

The color match should finish up the look nicely good luck and welcome to PT.net

thanks guys, blackjack im actually hesitant on the 3k because of my truck being lifted, if it should be lower than that. reason for 4.88's is to have that extra performance down low. also helps for hills and country areas im in. granted ill be pulling 2500 rpm's vs. 2300 rpms with 4.56's but its not that extremely different. better accelleration around town is what the difference is. i might change it up for 4.56's though.

been looking at the TR 220 112lsa cam, i think thats what i would want, gotta look into it more because i saw a few comp cams 218. im still reading through the other forums and such about cams. trying to see what everyone has gone with since im looking for performance outta my daily driver.


a tranny cooler like this?trans cooler

gotta figure out how to beef up the shitty 4l60e, wish i had the 6l80e. all i can think of is the cooler, the vette servo, thats it.

I have a 3200 converter and vette servo and that by far was the best mod to my 09...I also did the trans cooler but I would do gears and converter before anything else. It put the fun back into driving a big truck IMO.

Great looking truck BTW!

thanks man. the 3200 stall wasnt obnoxious? i figure a 3k stall on my truck would be a little much being lifted and all with the big tires.

Not at all. Say in normal driving situations your truck starts to take off at like 1200ish, mine starts to take off at 1800ish. Stomp on it and it flashes to about 3000ish. All of my friends that have driven it cannot believe the difference in performance. I had never riden in anything with a looser converter but I would not hesitate to get another one. Call Chris at Circle D and talk to him about any concerns you have.
