Good so it's not depo racing IC, maybe a leak somewhere? Coz I am about to buy a depo racing 3.5 and I also got FRPP like op.
I almost got depo racing IC a long while ago but had other expenses, anyways depo racing IC is still the same decent quality as before right? Gonna wait and see what kind of discount they offer for the holidays.

How's ATP FMIC? That's a little more expensive but will work with ATP flange and works with HKS BOV, really like the sound but back and forth and the extra cost vs depo 350 bucks!
I have NO complaints here, Depo 3.5" for a few months and the pulls are very consistent. The quality is top notch and you will still need to get a couple of nuts for the lower mounting tabs. Any and all variation of a front mount, being a larger volume will add a small amount of lag. You decide if you really need an IC and could live with the added lag. If you tune you may notice it a bit less, if you don't you may may still notice it but then many claim they don't it all depends of how your level of OCD is.

If i were to do it again, i probably wouldn't have done it but for the price you cant beat it. I daily drive my car so the stock IC was fine but now thinking forward to a couple of track days, im glad i have it.

I am not saying it's Depo problem. I think it's the lag I'm feeling. I don't think I would feel it on the stock tune. with the Ford performance tune it was instant power. It felt more like my 88 Mustang GT than a turbo 4. In 1 at about 2500 rpms I could give it about 3\4 throttle and the tires would ignite. Now nothing. If I would have a warranty problem I would put the stock IC back on before tacking it in. I have about a year and half on the warranty. After that I will get a custom tune.
 
Depo “beast” customer here. Very satisfied and would do it again. It’s a great value FMIC.

One of the bolt channels was too narrow for the provided bolts. I spent ~30 minutes at Lowe’s finding a bolt that would fit.

I was going Go to the beach they decided to save my money for something else Tim said it wouldn’t be really worth it for what I’m running

Update* I removed the bumper cover and replaced the bad o-ring on the map sensor. I removed the tubes going to the intercooler and replaced the clamps with T-bolt clamps. I did the hair spray trick to slip the boost hoses onto the intercooler to help seal them. I also added a ground wire from the -battery wire to the frame as described in another post. After taking it for a ride it felt about the same. The cooler it got outside and the more I drove it the better it got. With it in the 30s out it now lights up the tires in 2nd like it did in 1st. I am afraid when summer comes it will go back to being sluggish.

Does the boost gage get it's info before or after the intercooler?

Since we were on the discussion of intercoolers and turbo lag on page 1 of this thread, I'd like to personally note that the redesigned CPE lightweight intercooler (with the diverters in the end tanks) doesn't interoduce any noticeable lag on the stock tune. That being said, under their product description they do mention lag was one of the areas of concern when redesigning this particular IC, so whatever they did to this unit addresses the issues that other ones have.
 
What kind of peak boost are you hitting? Is it simply the lag you're feeling but still reaching more power? I've also had Depo for over a year now and never noticed any differences between summer/winter and I'm in the PNW

somewhere around 24-25 the same as before the intercooler upgrade. I would go to WOT at around 2500 rpm and it would accelerate slowly then like a switch it would hit power. Even in power it would not spin the wheels in 2nd. It would before the upgrade. After driving it for a while it seems like the computer needed to relearn things. It is not my daily driver so I don’t put a lot of miles on it. The more I drove it the better it felt. Now It is just as good as it was or better.

I installed the 3.5 Depot sometime in 2018. And yes there were some lag compared to stock. Most of the time I could detect the lag going up the parking structure. The car was running better than stock for sure, considering the summer heat in Phoenix, it was pretty good. Just two weeks ago, I replaced the cold side horse with a hard pipe; hollycow, there is no lag what so ever. It has been 2 weeks and the computer has dial down the intitial responsiveness from resetting the ECU, but no lag. What I am trying to say is the depot has no lag; it is the stock tiny cold side horse that is the choking point in the system.

Thanks for the info. I will look into replacing the pipes. I was looking at replacing the throttle body with the RS one and add a spacer. They are supposed to improve throttle response and add some torque.

I think it's the mustang throttle body that we use but I could be wrong.
Sorry, I think it is the mustang throttle body.

I had a spacer and has to remove it to install the cold pipe. The aftermarket pipe is larger than stock and being metal there is not much room to deviate from. Mine hit the oil filter if I left the spacer in place. I suppose it might fit if I cut short the silicon coupling hose, but did not want to mess with that.

Did you feel a difference when you put the spacer on?
