Default Dynoed the Purple Car today....

Dyno Info/Chart here

Overally, for having everything it does, I'm not too pleased with the output. Granted, I'm still on a stock throttlebody, and the tune DEFINITELY needs some more work just by looking at the A/F ratio (the car was NOT detonating or anything at least), but 260/195@.550 flowing ported heads and a hotcam shouldn't be that low. TQ was good, but I have a feeling that may be gearing related more than anything. Hopefully I can come up with the cash to get the tune worked on over the next month before the next dyno day.

What do you all think??

Those #s dont seem to be that far off , running lean isnt helping you, what are the other mods you have done, Is the car an A4 car.

No, it's an M6 car. For performance mods, it's got:

GM Hotcam Kit
Ported Heads
K&N CAI
Holley Airfoil
Mac headers
Mac ORP
Flowmaster cat back with Dynomax muffler
PCM For less tuning
SVO 24# injectors
Meziere Electric Water Pump

I think the major hold ups are the tuning, cat-back system, and stock throttlebody. Once it gets tuned in I'm expecting to see at least 350+

Also, the car is really undergeared. It is an M6 swap, and has a built 95 T-56 with a 3.23 gear ratio in the rear.

Im not a fan of mail order tunes, seeing how cheap tunercat is I would invest in a program you can take to the dyno and make the adjustments there. I cant see the catback bothering you thatmuch, maybe the TB is costing you 5hp but I beleive you will find your power in a good dyno tune , between timing and fuel.

I have tunercat. I just don't have any tuning experience.

The tune is from the Chip Guy at PCM For Less, and he and I speak pretty frequently. He is THE MAN when it comes to tuning 93's. He almost had my black car nailed on the first shot, and short of dyno tuning he's the best thing. I was making datamaster logs and he was tuning off of those. The tune in the car I'm speaking about in this post is an initial, first shot tune for the previous of the owner. It's about 1 1/2 years old, and the previous owner never had any adjustments made.

Nada yet. Motor should be shipped back in about 2-3 more weeks, and I'm still waiting on head flow numbers so I can give the cam guy a call. I'm hoping to be running again on April 25th for a dyno day nearby.

fastbird93 ---- I had to reply to this after I saw the subject of this thread---- I also own a 1993 Purple Pearl T/A M6 that has about 75,000 on it. I have only seen one other one before. I have been looking for a ram air hood but haven't decided which one to get yet. Yours looks really nice as do the rest of the pics!!

SWEET RIDE!!!!!

94Formula/TA, the dyno day will be at Xotic Motorsports in Cochranville PA. www.xoticmotorsports.com -- also check the North-Eastern Forum on www.camaroz28.com.

jrod07, thanks for the compliments man. I bought the car just like she sits too. I've been looking for production numbers breakdown by color, but haven't found anything yet. I know it's one of the more rare colors. Which M6 do you have?? The M28 or M28?? Mine is an M6 swap, it was originally an A4.

I contacted Pontiac Historical Services and a while back and they sent me the production numbers for free (but I can't find the email right now - sorry) and I was planning on getting a full vehicle history report on it for $35 but haven't done it yet. They are very informative.

My tranny is an M29

Lol, that's one way. Very nice looking ride. I may ****** one of those short sticks up too. I have a hurst shifter in mine and the fiancee who drives it most wanted one.

jrod07, seeing as how you have a 93, have you checked out the speed density forum yet?? It's 92-93 specific for LT1's, you may like it. Link in sig.

Thanks a lot for the compliment. I'll have to check out that forum later. Also, if you want a short stick, just PM me. I have them ready to ship Priority Mail.
