The car made 230-235 on a Mustange Dyno and a Gtech.
Seem ok for the injector HP rating. Well the car started runing a little rich latley and runing ruff. So I decide to strap the car on a Dyno jet and I dyno 258 HP to the wheels. I was like that is imposssible. Turns out I should have use A dyno Jet to go by, the injectors have been working ok but at 91% from what the dyno jet stated my HP was. Pulled the injectors at the shop and tested them the injector were failing they are leak streams of gas at random times, they are shot but at least there is no motor damage.
I have to say that lucas injectors are die hard. I am ordering 60s and will install them.
So test using a dyno jet higher HP numbers are safer for tuning and testing.

 

Yeah you will definately want 60's. The 42's are way over duty cycle with a 2.6" pulley. Most people put 60's in with a 2.7" or 2.8" pulley.

 

get your car tuned are you crazy why are you using a maf-t

 

Didnt the Mustang dyno operator tell you that Mustang dyno #'s are ALWAYS 10-15% lower than dynojet #'s? I prefer Mustang dyno testing vs dynojet as the y are more accurate and you can do better testing with them. Itshould have been obvious from the Mustang dyno the injectors were being over worked unless that operator was new or didnt have a clue.

Also each dyno operarator is gonna get a little different numbers even from same brand dyno to the next. Had a test car and did a set of runs on a dynojet, 20 mins went down the road and had 21 rwhp difference between 2 exact same dynos.
