dyno tuning saves TONS of time and in almost every case, will outperform a street tune that someone has been working on for weeks. </thread>

^^^ ya thats not really that good, most GTPs run 14.8 stock. Some have gone 14.5s

my 98 went 14.6, stock, the 1st time I every raced back in 03 I think it was? 14.3 with the 1st johnny airbox, a handfull of 13.9s with a 3.4

Also rarely the most trimming without knock makes the best power. Something you don't know street tuning a car.

I daily drive my car 20 to and 20 from work everyday. I beat it pretty good from time to time, and really only when I gank the throttle in fourth going up a hill do I see any KR that would concern me. I bought the car with 35 thousand on the clock, and now it has almost 43 thousand. I bought the car about a year a three months ago. Knock on wood the only thing I've had to replace was fluids, plugs, and tires.

There's not doubt in my mind a street tune can be as good or better than a dyno tune for street use. Dyno is certainly safer. Especially if the street tune is done W/O a wideband.

Plus all improvements are only relative to ones own butt on the street unless doing a true 1/4 mile run. A dyno is certainly going to let your vehicle perform to fullest when you put the pedal to the floor.

New Era did a great job on my grand prix. Even if it doesn't like to be hooked up to a dyno easily Razz

Plus its cheaper for "retunes". They have a discounted re-tune rate.

Adding some rolling weight to the car this year (compg vs torque wheels) my car still ran a low 13.9 in hot wet weather.

The 13.7 was run in the fall, but the 14.1 or 14.2 was run not much earlier than that w/o the tune and 6-8 degrees of knock, yeah that probably cleaned the tops of my pistons possibly.

I'm running less than stock timing but times that are much better. Crusing on the otherhand timing is bumped and my fuel mileage is great on the highway.

I ran a 14.5 with Racegas, my "intake", and the downpipe/resonator combo I have. (was seeing 3-4* of knock so I tried the race gas and it worked.)

For a 3.5 pulley, I'm happy. Heck I don't even have a "CAI" in the traditional sense.

Only thing I could be happer with is the transmission shifting. Its ok, but I still do better ET's when I do it myself in tapshift mode. (Have the timeing when to hit it perfect now Smile

)

Oh yeah did I mention this trip:
http://forum.unycgp.com/unycgp/viewtopic.php?t=5764&highlight=
5400miles (car drove 3500), top speed of 140mph. Every type of fuel you could think of Smile

24-25+ avg MPG and the "moving average mph" my garmin picked up was 65.6 mph, that including the trucks speeds.

There's no doubt in my mind that they are good at what they do. With that said, I'm sure not all Dyno shops are created equal.

So, getting a degree and taking some math classes makes you an expert tuner? I'd rather have the guy who has been tuning cars for years with a high school diploma tune my car than some seat of my ass tune. I have an HPtuners and a wideband so I'll tune it as best as I can and then I'll carry my little a$$ over to the dyno sometime this fall and have them see where they can squeeze some more out of here. So I should be a master mechanic too right I mean I've worked on a few cars this week in my driveway so that makes me an expert on everything with four wheels? Thats pretty much what you're saying, you have tuned a few cars and don't trust dyno's, so don't take your shit to the dyno go hang out with your kiddie friends at McDonalds and talk about the new stickers on your cars.
