My max power for the day was 216 hp and 250 tq. When I took it in my air fuel was 14 something. They stopped the pull and brought it down to the low 13's. After that we couldn't figure out why it was pinging. After about 12 pulls they said to come back tommorow and their master tuner would be in and he could look at it. We adjusted the timing all over the place and they suspect the plugs and maybe the coil. It didn't cost me anything for today and only 100 bucks for tommorow. With my mods could I reasonably expect more out of it with a better tune? They used a dynajet. The graph was ugly and bounced all over the place, I assume from the timing or plug issues I was having. I'll have dyno sheets tommorow. What do you guys think? Am I getting ripped off, whats my status? I feel like I'm getting a decent deal. Most imporantly, could I expect more power? Mods in the sig.

hp sounds good for stock intake and heads. were you running the chip while on the dyno? also what grade fuel were you using

Not bad really..You really need to get an intake on it to gain more...looks like you still have the stocker???

For 100.00 and all those pulls, plus tomorrow... I'd say you did just fine...Tuning wise all you can really play with is the timing and fuel...once you find those sweet spots, its a done deal...

Pinging??? that can be a host of issues...i wont even go there...are the plugs fairly new, gapped correctly??? Tell me they pulled the spout when tweaking the timing??? The state of tune makes a big dif....wires, filters, clean MAF and TB...all the basic stuff needs to be in order when you go to dyno it, least to me anyway..

It also might be valve float from ****ty stock worn out valve springs with the high lift of that B303 cam. But hopefully its not, although it happend to me. With my stock cam and 1.7 rockers

I wasn't running the chip on the dyno, my fuel was 93 octane and the runs were made with the spout disconnected. Hope I don't have valve float... that would suck...

If I had 3.73 gears could I get into the 13's on street tires with decent driving?

Decent driving? Prob not. But some good driving should get you there. Drag radials will REALLY help your cause IMO.

Drag Radials? Thats not really what I had in mind. I would like to end up running low 13's to mid 12's on street tires... I guess I'm going to have to go after a new intake and heads...

With an Intake you'll have a better shot I think. It will help you pull a little harder at the top of the tach. If you did heads you'll be deep in the 13's for sure.

I was reading some of the other posts on here and some people are posting higher hp and much higher tq than I am with similiar or less mods... what gives? Is the *tune* going to make that much of a difference?

I guess the saying would be "Dyno it like you stole it?" I don't know... I kept the spout out cause thats how I was running before. I had some timing issues and it seemed that either way I turned the distributor would make it worse. So I pulled the spout, bumped the timing WAY up and it ran great. Then these guys do their thing and it's running better with the spout in like it's supposed to... Damn professionals... always fixing a perfectly f**ked up stang... In reality I'm just glad their on the case...

I don't know.. it works now... I'm going to let the expert do his thing tommorow. I have a question though, don't you just love the way these things sound at full tilt? I've never stood behind it with it running like that... very awesome... I'd buy the car based on the sound alone...

I dynoed 214/278 With only a catback and pullies. It's in STD HP. But converted it was less than 2% difference. It was on a Dynojet 248c and the motor had 106k

Have you checked the compression, is the cam advanced or retarded. Personally, I think you should be in the 225-235 range. What where they pulling it to. I had issues after my HCI with missing at upper rpms. Overhaul of the ignition cured it and in a hurry. You could have multliple small issues causing an overall degradation
.
I know how frustrating the dyno can be. Last time I spent 6 hours on it. Man...did I have issues after the blower install. I pegged the MAF voltage, maxed the injectors and was blowing out the spark Couldn't get passed 5500 rpm A custom chip helped some, a MSD box and regapping the plugs helped too. But I admit I was disappointed by only 385/414. All that to find out I needed bigger injectors and to spend MORE money.

You will get through it.... although as most anyone can tell you spending money in one area makes it mandatory to upgrade and spend more in other areas to optimize the foundation of the combo.

I have the dyno graph... The torque curve is great, almost flat... Love V8's... It's in SAE, in STD I made 221hp and 286tq.. let me scan it and show you guys... as it stands though I made 215.2hp and 279.7tq. He fattened up my fuel a bit, advance the timing a bit and found a rather large vacuum leak from the PCV... he fixed that though...

You will have to resize the pic prior to trying to post. Or upload it elsewhere and link it.

PM me and if you want I can host and post it for you.

Your #'s sound much better in SAE.
