Add a spectre intake filter and your getting some awesome sounds with the vortec...

I just used the aird tbi spacer it was alright ,but i used the cfm one of my buddys truck it woke it up event with the injector spacer too.I think i got 2 mpg increase and i can fell alittle more power not much to make you scream for joy ,but i think its worth it.

Been wondering if the K&N FIPK gives my TBI any noticeable gains or if the swooping sound just make you **think** it does ????

 

[1990GMCSIERRA]

u just floor it more to hear the sound
so its really not helpin ur mpgs lol
i said **** gas milage along time ago

 

[Bigg G]

I definetly put more foot on the gas than I used to.
Can't help though because it sounds so darn good LMAO

 

[1990GMCSIERRA]

1990GMC i like your theory.... F*CK gas mileage I think the same way!

if u want better mpgs u could always clean ur canouter valve,
u dont wana let it stop up cuz if it does ull blow the gasket on ur wobble shaft and then ur centrifical clutch will be shot all to hell lol

if ur gona go with a spacer id get the one with one cut in it instead of the 2 holes
