    99 tahoe ppv spider injection

    The spider injection system should not cost $900. Look at Amazon or Rock Auto. Should be around $300. If the one without the hold down bracket is cheaper, get that. You don't need it unless your bracket is broken. The MPFI unit is the one to get, not the poppet style. It does have a...

    Thanks man! It's a build in process, and learning a lot along the way. They never road tested it, due to open exhaust manifolds :rolleyes:, so now it's back with full exhaust. Just like I was thinking, they say it's a fluid flow issue. Hopefully I didn't destroy it too much in the last 100 miles...

    exhaust where to go

    You will need 4 O2 sensors. If you only run 2, you will need a special tune from someone like @BlackBearPerf , or others, in order to tune those downstream sensors out. At that point in time, you might as well do a cat delete, and have fun! I'd talk to exhaust shops near you and see who can...

    Back to the transmission shop today so they can finally test drive it properly. They have 2 weeks to get it right!

    1999 Tahoe Engine VIN

    Welcome to the forum! 8th letter of your VIN will tell you which motor it is. If it's R, it will be the Vortev 5.7. Do you have any pictures of the engine? On the driver's side rear of the block, by the transmission, should be stamped 5.7 or 5.0.

    NEED MO POWA!!! Can't wait to get that 488 in the garage and start building it. With low compression and forged internals, can't wait to run some nitrous on her. Swap out the cam, heads, and intake. What fuel injected intake do you guys recommend? I found an oval port Edelbrock Pro Flo Xt, but...

    You'll see it didn't start or idle the best, but it's due to too much fuel pressure. Doesn't always do this, but just need to swap our fuel pressure regulators. I'll get a better video next time, and I'll get one while driving. EDIT: uploaded a different video

    Drove the Hoe home and my GAHD does it sound beautiful! Idk if video clips will do it justice. Under light to medium throttle, it's deep and throaty, but when you get into it it's raspy and deep!
