3.5" TB and spacer
Please refer to post #45 on this thread.
we will try this Thanks
Ok so we have 21 now! so the price will be $49.99
This GB will end on the 11th
Please just log the MAP1 (before SC) at WOT (before and after the new TB) with one of your 3" intake. You'll see if the stock TB is restrictive !
Personnaly, now with a 2.9" pulley (boosting only 12 PSI at Alberta altitude), stock intake with a K&N air flow filter, I get only 0.2 - 0.4 PSI max of restriction from the stock TB, stock intake and high flow filter.
Also, I can remember at see level with a 2.6" pulley boosting around 19 PSI, I was seeing 1,5 PSI restriction with the stock intake and stock filter.

i wonder if there would be any tuning needed if you have a stage 2 from gm. if this increases air flow, then instead of getting a 2.9 pulley, you could have this instead with less heat and same amount of power. i might be in depending how testing on the stage 2 they are testinng goes.
All these vehicles listed, are able to use the 4.2L as a direct bolt on, without modifications.
