Another satisfied customer. Thanks for the updates. Enjoy it! Let's face it, EVERY manufacturer has had a run in with recieving bad parts, just a part of the business. They recognized the issue and they are fixing it. I am glad that you got good customer service. That's what it is all about.

 

Glad everything worked out

 

Sure I have a comment ? I'd like to know how the jumper harness and maf sensor is able to get rid of throttle lag, being that Ford programmed it into the PCM as part of the stock tuning files ?...I thought only a re-flash of the PCM was capable of eliminating throttle lag..

 

It is my own personal experience and belief, that the CAI itself is what mainly gets rid of throttle lag. I used to have it bad on my car, and it lessened a lot just by installing my CAI. However, after reading another thread in another forum, I started evaluating my driving habits, and being that my car is also my daily driver as well as an auto, I found that I was driving my car like I drove my SUV before her.

In the thread the guy stated that you should not drive your car like a Grandma, that it is in fact a sports car and should be treated as such. So, I started changing my driving habits, driving more aggresively, and after a week or two, my throttle lag had pretty much disappeared. Now, I won't believe that is mere coincidence, but to add to this, I have recently removed my CAI and put the stock back on for dealership stuff, but 2 days after I put the stock intake back on, I was driving, and went to stomp on the pedal, and there it was again, that second delay throttle lag.

 

I don't know that it gets rid of the throttle lag, but rather there is sufficiently more torque down at the low end that it just seems to get off the line faster. Look at the Granatelli dyno curves.

 

After reading all the posts here and also the Dyno results for the guys that went to St. Louis. I am wondering if I made a mistake buying the GMS w\MAF. For warantee purposes I did not want to change the tune, now, from reading everything the CAI may need a tune. I am afraid to drive the car with bad A/F Ratios. I am trying to schedule a dyno test just to see where the A/F Ratio is with my car. I bought the CAI thinking that I would not have to do this...but...I am happy with the performance of the product just a little leary that it may cause damage. Thoughts? Anybody else wondering about this?

 

If you have any doubts at all, do yourself a great favor. GET IT ON A DYNO! I have no interest in bashing the GMS products. But, it does seem strange to me their product does not need a tune and all others do.

Don't worry about blowing up your car, if it is dangerously lean you will get a CEL. Get your dyno done, and see for yourself how your car is running, and then go from there.

 

As I said, I have found a local shop that does Dyno testing and I am waiting to hear from them to get it scheduled. If I see any CEL then the stock part goes back on. No biggie. I will let you know the dyno results that I get.

 

Good luck, and post your results either way. I am finding it very very very very hard to believe that I was lucky enough to get the only Magical GMS CAI that works.

 

05GTRedfire: I will post them as soon as I get it done. I just need the peace of mind to know I did not waste my money for a CAI that may need a tune. That was the main reason I bought it in the first place, just as many others. Just waiting to hear from the shop.

 

Redfire ? it's not that you were lucky enough to wind up with the only magical GMS that works lol.. it's because each car is calibrated differently even if their indentical cars ? each car responds to mods or tuning differently plus it also depends on factors such as temp, humidity and altitude conditions which can also affect A/F readings..This is why it's always a good idea to get tested..

 

I also forgot to mention that metroplex mentioned something along the lines about the air transfer function, can also reduce throttle lag although I don't know this for certain

 

Well again, all I read about was how only a tune can get rid of throttle lag, and I ended up having none, without one.

 

And if Metroplex is correct about the air transfer function ? then I'm pretty certain that either the GMS maf sensor and or jumper harness somehow has to modify the transfer function in order to function properly.. I should ask Doug about this, just to be sure..

 

Well, 3rd and final harness came in and...WE HAVE A WINNER! Finally after ordering the thing Oct 9th, I get it to work on Nov 17th! Wow what a difference. The "power lag" is almost gone, gas milage remains about the same, and the thing SOUNDS INCREDIBLE above 3000RPM compared with stock. Revs much more freely, etc--- you get the point. Don't have a dyno nor the money to bother with one, but from feeling...yeah. I'd say I got that 25+HP or close to it. Either way, I got rid of the "power lag" which is the main thing I was aiming to do. Does it work? Absolutely. Is it worth $400? I'd say so.

I'd be inclined to agree with you. The 1 second between pedal down and go is still there, and the length of time is exactly the same as it was before. But it definitely pulls more strongly right away once it does go.

 

Glad to see yours work out like mine did. Still happy with it today. Definite improvement in performance and sound. I don't think it gets rid of the "throttle lag", it simply delivers more torque off the line to overcome it.

 

I'm also glad to hear you got everything worked out. It always surprises me to see negative comments about GMS, and honestly prior to this I had never ordered anything from them, so maybe they had a change in policy, I don't know. But all I have seen in post after post is their customer service coming through. it does suck that anyone would have to go through this, but if it were a perfect world, blah blah blah. Anyways, grats, and if you try stabbing the pedal some(a week), get it used to responding to instant gas requests instead of gradual ones, it might get rid of the rest of that delay.

 

Well I just got my second harness and have done the install. HOLY COW!!! This thing is amazing. Instant power increase that I can feel. Sound is incredible. GMS customer service has been great.

Now it is time to order my FRPP ceramic shorty headers, FRPP X-pipe, and GTAs.

 

Boy, with all of these happy GMS customers, this can't be going the way the topic was meant to go... It just proves that there is a lot of unsubstantiated BS out there and it's not just about GMS. If you noticed, the naysayers never had the experiences, it was just something they "heard". Your never going to make everybody happy but I will never post something that I have not personally experienced (or at least not known the person that did experience it). This post is what TMS is all about. Nuttin but the facts mam......
