Alright so my car has the following mods and i think I'm making less power than I should be: Bushcur 2.3 stroker, Stage 3 built head, gsc s2 cams, stock turbo (unfortunately), ets intercooler, o2 dump, ported manifold, and probably some other stuff I can't remember. About a month ago i had my car tuned by prime motoring and only made 298 whp/ 290 wtq. It was a very hot summer day but still I thought these numbers were a little low. I have no boost leak the car hits 26 psi and holds strong. Could there be any other reasons that my car isn't make as much power as it should? Thanks in advance.

 

wow, even on a mustang dyno that seems very low. please post a dyno plot?

 

What type of dyno, what compression ratio, what was the ambient air temps, what correction factor if any was used?

 

Ok I had my numbers a little off here's my dyno sheet... 286whp/308wtq

 

Did Junior tune this?

What did the tuner say?

 

Yes it was tuned by Junior and he told me that in order to make more power I'd have to get bigger injectors. I'm just having a hard time believing that my injectors are maxed out at less than 300 wheel.

 

Not surprised about Jr tuning another vehicle at a subpar level. Sorry to hear

 

Are you on stock injectors, fuel pump?
Did you do a boost leak check?

More detail, I made more power on my stock turbo on BR's MD dyno... in my sig....

 

I think that power looks about spot on with the factory injectors. You have to remember a 2.3L requires more fuel then a 2.0L also. Why not just get bigger injectors before getting it tuned. 1000cc are very cheap.

 

okay well if on stock injectors, Yes it looks right. get some 1000+cc injectors and retune.

 

Looks about right on a Mustang Dyno with stock injectors, stock turbo and pump gas.

with your mods you should be around 350-380awhp.

 

yes, it is going to have lots of torque if on stock turbo. Add some e85 and you will really feel the kick.
