...the plugs may be a little too cold as well...

Meybe or they are ?????

well if 24's or 25's are recommended then yes the 23's are too cold...

well its not because the meter is from a foxbody...plenty of guys run fox body meters on our cars...the fact that its a 75mm may not be helping as they are hit or miss...some work on our cars, some dont...the plugs may be a little too cold as well...

Our timing/fuel tables are the same as foxes? I thought they were different. If they are the same, then why arent the MAF's sold as 87-95? What ever small difference they have must be able to affect the performance, otherwise they wouldnlt be in seperate categories.

I know a guy with a 95 cobra who put a A9L computer in it with a 351 and ran 94-95 mafs/ electronics and the timing was TERRIBLY messed up.

Im no pro, but get the tweecer man. Tune it for a 94-95 and you should be set to go.

i think the meters are just built different...i think its the way it attaches (flages or something) i know for a fact Joe(Vib) ran a Fox meter on his car....i believe the electronics are the same for the fox cars and ours...the eec takes care of the rest...

Well they have MAF's with flanges and ones without. But i dont know....

Either way, he needs to get a tweecer.

 

[VIPERn94Five-0]

i cant remember what exactly is different about the 2...but i know we can use theirs...the MAF really only reads how fast the incoming air cools the little sensor things and relays that to the EEC...not much more...

and i agree he needs a tune...either a tweecer or get a full on dyno tune with a custom chip...

I have 3923's in mine all the time. I use this cold of a plug for Nitrous. I always run these plugs NA as well. I have never had pinging issues. SO I dont think its the plug. But I dont recommend the 3923 for you with no power adder. I would get 3924's.

I just swap plugs with 3924 with .42 gap

Fuel couse pinging, last night I pump with new 93 octane and now ping just in 5th gear, I still have timing on 10*, meybe I should bump to 14* again ?????
Whats is the best timing with aftermarket heads and cam
