What are you using for headers?
i had long tube Dougs on the engine and they were fine with the engine but they didnt fit in the car. i ordered a set from dyno don. im waiting for them to come. says 8-10 weeks. its been almost 6 weeks. so i have a lot of time to get the wiring done before they get here. I'm told that dyno dons are about as good as it gets for a thirdgen. the Dougs headers are very nice. im going to put them in my 1953 chevy truck to replace the headmans that are in it now.

i got through some wiring removal and the driver side dyno don header on. the driver side is the more difficult side but it wasnt too bad. i will get to the passenger side this week. on a side note look how massive the runners on the first tpi unit are.

New plugs. Figured out my spark/fueling issue was a completely disconnected plug wire. Ridiculous.
