I have a 93 mustang coupe with a stock lq4 bottom end with unported 243 a custom eps cam and victor jr with a 850 holley and at 3200lb the car went 11.13@121.8 .dont know if im in the ballpark or do i need to do more tuning.

 

manual? automatic? How much stall and cam?

 

Cam is 234-246 601-606 on a 109
Stall is 8" Hughes 4200
Gears are 373 with 27"×11.50 quick time pros.

 

What 60'? Id think you should be in the 10s, but you right in the ballpark.

 

1.58 60foot. I also been told to change my timing controller it is the elderbrock by msd and I'm run the#6 chip I'm told it puts 36deg. And I only need around 29 to 30

 

With a 1.58 60' that does not sound bad at all.

Timing will for sure affect ET and will also affect your tune and A/F ratios. Tune for the highest MPH.

Also what was the air like and your altitude? 11.13@121.8 is a nice run but if your tune is off 1/10 is not a lot to gain.

Regards,
Bruce

 

I think you have some 10s in there for sure too.

I would make this upgrade immediately. You need to be able to have complete control over your ignition. There is surely some ET in the timing.

 

Back the timing down to 28-30 and work on the 60' and you'll be solidly in the 10's.
