sounds like that dyno reads low if it was the same shop. a bone stock 951 should dyno ~190 whp, S's have been known to lay down 220+ at the wheels in factory trim. Also how did the car do 300 whp at 3400 rpm, but only pull 276 whp... I'm confused. I wouldnt be worried about it though until after you drive it. Take it for a spin, if the car pulls hard down worry about it. Also, are you still using the AFM or have you gone to MAF? 300 whp isnt bad if you are still on the afm..

Guys, I'm disappointed after the shop that tune my car say he tune the car at a SAFE 18 psi and he only got 276 hp. First the engine is freshly build 2.5, light crank, super 60 turbo, 70 psi injectors, stage 1 head (lindsey), using a Electromotive TEC -S, 3 inch exhaust, tune with 93octane gas. Some people claim 300hp on stock engines adding chips. I'm I wrong??
1. that's a ton of power on a Mustang dyno.
2. it's not a V8.
3. be happy.
4. life is good (and you might really learn this if you don't stop reving the f_ck out of the sum bitch).

With just guru racing chips and 3bar fpr and shimmed wastegate, peaking at 15-16psi, I dynod 250hp at the wheels, or about 275bhp on the same dyno same day install.
Your car should be making closer to 365bhp if everything is tight and tuned right.

another reason to just go to a local drag strip and take off easy and get a MPH. That will tell you definitively how much HP you are making.
Dynos are only good for reading curves and making changes using the same dyno. Comparing numbers to other dynos is a waste of brain cells IMO

Please don't turn into a dyno queen. We have enough of them around here already.
It's a tool to use to help you get the best performance out of your car. I try to use the same dyno and operator every time I use one and I don't typically share my results with anyone. If you want bragging rights, let's take it to the track.
