Performance Chip Question

At Mr. Crowley's site, he mentiones the removal of secondaries as a feature in his performance chips. What the junk is that about? Anybody?

I believe he'll add programming to deal with the removal of the secondaries if you've done that to your car.

Not being too mechanical, I don't understand the reasoning of removing the secondaries. I thought that was so special to the Z's.

I think it is a case of having both injectors serving the fuel needs all the time. I believe Cliff, LoTu5, from London has this set up on a 418 cu in motor. I don't understand all of the theory behind it. I guess you eliminate all those secondary parts so they can't fail on you?

A thought...I would guess when the motor gets on the cams the transition is less dramatic? I mean nothing is blocking the air flow thru the other ports and the injectors are already adjusting the A/F ratio so the big power is just there all the time?? I'm wondering if those cars must feel like an old rat motor from the 60's & 70's? I once drove my friend's 396/350 camaro & it was way different than my LT-1. The 396 felt like a stump puller from way down low in the rev band where the sb needs to get some revs up before anything happens.

The stroker engine's may benefit from removing the secondaries. Tuning is a fine tooth blade also.
For a stock CUI or even a 368 car removing the secondaries would probably hurt the car .

I'm more impressed with the top end car's putting out 420 + RWHP .

My sentiments exactly... Thats my goal actually. Squeeze as much out of the top end/exhaust and other small things here and there without changing the displacement. Although im still alittle uneasy about porting for some reason, I just dont like the idea of taking metal off. Tweeks a nerve in me. :icon_scra
