2004 5.3 silverado nickname Boobies with a custom 70mm turbo kit, cam, 80lb injectors and tuned for 91

I was really surprised but I know it needs fuel pump (not sure yet) and 4l80e

@7psi on stock pump it put down 446hp/457tq

ive got photobucket and never posted pics before hopefully this works







any questions comments or advice is appreciated and i will start a build thread soon

 

the cam in there helped out a bit. the 60e is going to hate life.

 

it feels strong but i still dont see it lasting long im looking for a 4l80e and have found a few options here in kansas city, im going to gather everything and do it all at once. its not my daily driver so i will be taking it easy on her. You were the one that tunned jaysons truck?

 

yep. once he gets the trans in it, it will be a whole new monster. it's on a backed down weak tune right now. trans hates life.

 

Looking forward to build thread with more info. Great looking truck BTW

 

I got a stupid question when i dropped the pan to tap it I had to drop the steering rack as well now the steering wheel is way off but still feels aligned do I just need an alignment redone?

 

Sounds like you let the wheel spin when the rack was unhooked. Do you have a service airbag light on?

 

no air bag light its possible it was hanging for a few days before i put it back on... no airbag light, but the ebrake and abs light were on for the start up but went away on the second start up. so drop it and i could straiten it out? or get an alignment?

 

Mine felt strong, for about 250 miles, lol. I hope yours does last though, give you more time to play with it before you swap. I can drive mine every day of the week no issue at all, but as soon as it builds any boost it slips. The ultimate blue *****.

 

Crusty, how was your experience with Justune? never heard of them, I'm located in Lawrence and just about finished with a turbo project that needs some dyno time, looking for someone I trust in the Kansas City area.
