My dyno run


The green is stock. The Blue is Dinan tuned. The red isJB4map5 with 50% e85, catless DP. Shouldn't the horsepower be higher?

3 things....

1-You should log when your run your car on the dyno

2-That ammount of e85 without a flash or meth could have caused your trims to top out. That could have reduced your HP.

3-Mustang dynos read lower

A LOT lower, I've found. 380whp on mustang gave me 435whp on dynojet. YMMV though.

The delta looks good!

Ya, I made 377whp and 404trq on a Mustang and that is WAY higher on a dynojet. When you switch a flash gotta let it adapt though!

Especially with the JB4 G5 ISO. And if your running a 50/50 mix, put it on map 7 and log it to be sure your not maxing anything out such as trims, timing, ign adv ect... Im on E63ish consistently every tank and run on map 7 full time. It def did worlds for me if it is enough octane... Havent taken it off since to be honest
