different. No tune-- no aftermarket air filter or system--- ZERO other mods.
Car previously went 12.52@115 (1.9 60')with the stock 3.42 on runflats.
Anybody know what is to be expected from this change???

I say 12.90@115 now, unless you change tires. Those runflats are horrible for drag racing and you will have more problems with those gear. Put a nice drag radial on there and I think you at least a 12.00. Good Luck!

I need to recap my original ET... Turns out as I peel through the slips in the console I made a 12.28@116 pass! Zero mods--- not even a K&N.
I bought the car used and it already had a Centerforce clutch in it and it was obvious the original exhaust had been removed and replaced before my purchase.
I think the car may have a tune in it??? This is a real slip at GLD in Wisconsin--- not a corrected et. 60' was a 1.92.
Still waiting for the 500 mi. break in to pass! Lotsa rain here last few days...
Bet it'll go a .90...
