what causes this rich condition? Recently did an intake swap to super Victor/ fast 4150 from a fast 92/92tb
I'm running speed density now
Car ran perfect with the fast intake but not worth a damn after the intake swap
Ever since the swap the car goes pig rich as soon as it reaches 40% tps... And it stays rich like 10-11 on wideband for anywhere from 15 secs to a minute... I've changed plugs,wires, and coil packs... Checked fuel pressure 58psi at idle and 58 under load... I have no clue what's going on... All the part throttle tune is dialed in and was starting to dial in above 4k rpms in power enrichment... I've pulled fuel out of everywhere above 4k rpms but it just stays rich after u blip the throttle
Anyone with some insight?

Well I started this thread because it's a fueling issue I think and I was curious to see if anybody had some thoughts on it... The other thread was to see if it's a tune issue..
Obviously nobody has any ideas in either section.. if there was another section I thought that it might get some feedback on then I would prolly post in it too

The guy in your other thread looks like he hit the nail on the head.
Once your steady state tuning is done I'd do a lot of work on your transient tables. Going from a plastic intake to a metal one is going to have a major impact on tau.
