having just purchased a new engine I had the choice to make to keep it with the CFI or not. I kept the CFI. Its what makes an 82 or 84 unique and I think I got better gas mileage with it. Not sure that will be the case with the new beast under the hood.

Ummmm. Crossfire's in a garage cabinet along with the stock block, sorry. :chuckle


I bought a superram on ebay and a 90 wire harness and a intake so I can use vortec heads with the superram. I still got to get fuel rails, injectors, new fuel lines, TB, and a few other things.

How fast does your vette go in 1/4 or on the street can you light em up for a block or two?

I am bidding on a 89 vette right now and I think I will put the superram on it instead of all the BS that goes into switching over from crossfire to TPI.

In an 89 if you just put the superram on and new heads, what would you get for HP? And what would you get for HP with a lingenfelter cam?

Still got the 84, but for now its got an xram. Pulled the crossfire to open the ports up on the crossfire, and am using the xram so I can still drive it everyday. Swapped it awhile back but have yet to port the crossfire. Seems something is always breaking(not the 84 usually) or work gets in way. Also keep getting the bug to work on the 71 vette. Thats a major work in progress.

If you have mods done to your CFI, please post them.

How does that x-ram perform?
Is there a major difference?
More top end, with the same bottem end?

Having seen the x-ram in person next ot a ported x-fire intake I recommend and did port my CFI intake. The x-ram guy is only 40 mins from where I live. Heres how my car has worked out so far. All runs were repeated to insure there were no flukes.

Stock- 15.3 @88
K&N and ram-air mod 15.2 @89
1.6-1 rockers 14.7@92

I added the ported intake-no more egr hump either, MSD box, wires, and NGK Iridiums, and rebuilt the trans. This 1/4 time includes the trans hanging the 2-3 upshift-you have to lift or let it pull to past 5500rpm
14.4@95
3.75 gears, still hanging the 2-3 upshift
14.3@96

working on the trans right now, my 60' time dropped .1 with the gears and the car is a rocket outta the corners at the scca events-love the gears. The intake works perfectly, ditch the swirl plates-you definately don't need 'em. My car is a daily driver and racer!

I havent been to the track, so all I can comment on is seat of the pants. Mine "feels" like it pulls better and revs higher. Used to feel like it was playing out at 4500, now still seems to be pulling, but I changed the cam when I changed the intake so that Im sure that has something to do with it. The cam is .442 lift and 214 duration with roller rockers. Plan on porting crossfire and putting it back on, the xram was a used one I bought just as a temporary.

Mine has 97k on it and runs awesome with the original CFI. Mine is bone stock except for a K&N air filter and gutted cat. I have had mine over 5 years and it has never given me a stitch of issues. I have a friend who knows how to set the cross fire and he did a fabulous job. I put some money into it when I first got it to bring it up to snuff but nothing after that. There is nothing really bad about the CFI. The bad rap it got was undeserved as it was GM who decided to mass produce a 2 TBI car and hope the generic settings would fit all the cars.
