slowly but surely building up this little beast. started with tvs1900 maggie, 3.4 pulley on 7psi, 1" 7/8 ottp long tubes. 3" exhaust, custom tune. she made 353rwhp and 419ftlbs of torque.

added a walbro 450 pump, boost reference regulator. 2.8 pulley. laid down and impressive 425rwhp and 480ftlbs on 11psi of boost. not bad for a daily driven street truck.

2009 gmc canyon cc, factory 5.3, rancho 4" , motometal 18" , 285/65/18 nitto trail grapplers. 5000lbs

Very nice! Are you sure that little thing weighs 5k? My 14 GMC was 4750 as it came stock.

Tell me that is a stock cam.....a 5.3 with 1 7/8 longtubes and 7psi only making 353hp is really low......11psi making 425 is still low....hmmm.

dselby25

yes stock cam, its 4wd and heavy wheel and tires. oh ya and its on a mustang "heart breaker" dyno

ZO6Ted

Yeah that stuff adds up quickly!
Well its just a tuning tool and to compare before and after anyway lol. Absolute #s vary so much dyno to dyno I understand. Great improvement though wasn't it!

dselby25

im certainly pleased with it so far. obviously hp is addicting so.... i want more. next time around will be cam, e85, maybe a bigger stall. we shall see tho!

Sweet truck those little trucks are a lot of fun. That thing is a heavy girl though! My ext cab 11 4x4 gmc only weighed in at 5080lbs and that's with tbss 22s.

OK Then. With a cam I bet you see more than 18hp per psi improvement too. I can't believe that thing weighs as much as a 1500. Wow.

dselby25

im new to the performance truck or performance market all together, but damn! really 18hp per psi? thats a ton!
