TUNING
Tuned on dynojet using sniper tuning software
Total Timing set to 26 degrees

DYNO NUMBERS
316rwhp @ 6300rpm
293.85 tq @ 5300rpm
Air Fuel Ratio 13.0-13.3 throughout pull
Curve is nice and flat not bumps just a steady increase to 6300 stays level till 6500 then starts to drop.


The car was broke in on the dyno. To set intial tune, no full throttle pull. The car was driven for approxiately 150-200 miles. It then was strapped to dyno for pulls car put down 309 with 22 degrees of total timing. Car was driven for about 100 more miles then retuned again putting down 310. Finally after driving car another 100 miles timing was up to 26 and the car put down 316.

The car doesnt smoke at all not, no leaks, no nothing.

Ok I just picked up the car. I am going to drive it for a week or so then bring it back for more tuning or whatever. The cars has a very noticeable cam in it. I mean the thing shakes likes crazy.

Currently the cars likes to die at lights on occasion, and the CAI sucks so much air it sounds like I have a turbo on it.

To me the cars runs a little rough, but I was told that was due to the cams.

By my seat of the pants measures, it doesn't feel as good as it did before. Before from a roll at ~15mph I could nail it and it would roast the tires and when I would hit second it would roast them again. Now at 15mph it doesn't spin at all and shifting to second yeilds a small chirp.

Car put down 320rwhp with a stock block with only CAI, ford racing shorty headers, basanni catted x-pipe, flowmaster catback, UDP, throttle body.


Just doesnt make sense that the car would not make more power. Most people with the similar setups make at least 335 where as most are above 350.

I dont see how it is possible to have only gained about 50 hp over stock with all the mods. Just the exhaust and intake should have put me there. On top of that it is putting out less then it had before the heads, cams, and better exhaust.

Any ideas as to what could be that problem?  

Any help or ideas are greatly appreciated.

Thanks

Update!

The car was running on 7 cyclinders due to a loose injector harness.  Car put down 370rwhp and 340tq.  I am hoping for 380-385 with a better tune A/F was a little lean at around 13.5 so I am going to fatten it up and throw more timing at her.
