<< Anyone on the list who has an MPI throttle body, I have a few ???'s for
you...
1. Which model (or stage, or whatever they call it) do you have?
2. How was it modified? I'm looking for a description here. Just looking
at it, describe to me the differences between before & after.
3. How much did it cost?
4. How long was your truck out of service, total? >>
A1. The model I have is the Super Street with the mystery shaft.
A2. The mods are, the tbi is ported and polished after being stripped down to
the last screw. Then it was coated (teflon I think) and it was polished
again. The throttle shaft is beveled to smooth airflow (looks like an airplane
airfoil) and the fastners are countersunk.
A2b. The difference I felt was incredible. There is no more low end lag, it
pulls hard from 900rpm, to 5400rpm (truck shifts here) The mid-range torque is
really great. Crusing along with the AC on at 1800rpm when I punch it down to
get thru the yellow light, it just digs in and flys.
A3. $475+$200 dep
A4. About 30 minutes. That is how long it took to install. Got mine
exchange.waited about 6-7 months to get it though. If ya have the extrd $$$
laying around, go buy a new one from CC and send it to Jules. He can turn it
in about 5 days, then sell him your core (he buys them) and you break even on
the new one.
Top it off with a K&N 14" Fipk and then hold on.
