03 Cobra

Baseline with 2.76 Upper and upper idler 90mm, JLT Carbon Intake, Accufab t/b & Plenum,Stegemeier Stage 3 port and High flow H-pipe, Flowmaster catback, Tuned by EFI Logics CT Mustang dyno numbers 472/439


New numbers with fuel upgrades (BAP,Mafia and 60Ib injectors) NGK Tr6 plugs 78" Gatorback belt. and 3 Ib LFP lower Max psi 17.7 average 16.1 to 13.6 and AFR 12.3. to12.1 average.

Mustang dyno 491/496 The peak hp/tq change 19/57. However, I compared the before and after numbers at a specific RPM and the increase is double across the rpm range.

For example 3200,4000, 4500,5500, rpms the increase ranges from 39-44 hp. From 5500 rpm to 6100 the hp drops to 19. I spend more time between 2000 rpm and 5500 rpm so I am very happy with the numbers. The car idles better than it did before. The only noticeable change is the Gatorback belt has a low hum sound at idle

What's wrong with the afr? Is it to high?

 

[CGLhawk260]

The AFR has Min 11.9 Max Average 12.3

 

[SVT03Chris]

Yes, too high for me. I would like to see it between 11.6-11.8 IMO. Everyone is different though.

 

[unforgiven]

Chris @ EFI tuned my 2.3 Whipple, I had him back off my A/F from 11.9 to 11.6. I lost 10hp but will sleep better.

 

[black02]

agreed 11.6 is the number to see imo...

 

[SVTkel]

The general consensus in the Terminator community is you will want to be between 11 and 12.

I would add 3% fuel on your handheld IMO
