Hey guys I'm new to the site , I have a 2008 silverado ccsb 5.3 with procharger p1sc1 8 psi gibson headers high flow cats 52# injectors 2600 TC eaton posi 3.73 gears 160* slp tt , this is a truck is heavy I got a big sound system (at least 700 lbs) and 28" wheels. It was tune by SoCal tuning and came out to 360 rwhp on stock 20" rims (what do you guy think about the results? ). Will install 4.11 gears this weekend but also want to change the sc pulley to a 10 psi , do you guys think my stock motor will be fine with 10 pounds of boost? I will try to upload some pictures tomorrow . Thanks

 

Those results sound a low to me on the rwhp, probably are low because of the 20" rims, what tires?

My truck only dyno'd at 267 rwhp with 20" wheels and 305/50 tires.

My mods were Tune, Headers, YPipe, Magnaflow, TStat, CAI.

And welcome to the site, post them pics when you can.

They sounded low to me too when I was at the dyno shop . The headers are shoties with high flow cats and single magnaflow . I want to get it to 10 psi of boost but don't know if the stock 5.3 will handle it.

 

yeah might wanna swap out the shorties for some LT's and maybe do a better exhaust, it could be choking up a bit. letting it breathe a bit more would help... 10lbs is a bit high but i'd be more worried about the tranny then the engine being able to handle it...
