Pros and Cons of Street Drivability off the kit Canned Carb EO Tune options with 91 Octane?

[Mustangpursuit]

I see many threads of mostly hp/tq and often just recommending custom tunes for all the kits over canned tunes.

But how about strictly just comparing or sharing experiences on which kits work the best when it is just limited to the carb eo tune that is provided without comparing hp, tq, Heat Soak etc.?

Such as desire for smooth shifting, all modes working (Adaptive cruise control, rain-snow mode) , no bucking/surging issues, mpg (not that it is important but can help with how efficient the tune is for driving within the speed limit and not flooring it)

Whipple 1/2 vs Roush 2 vs Procharger 1/2 vs Edelbrock 1/2 vs VMP etc. all under only 91 Octane with no additives.

I know many will disagree with me on this, but if you’re sticking with the CARB tune
then hands-down the best one is Roush. The supercharger could be better and the intercooler is terrible, but the tune is extremely well sorted and very oem-like in the way it operates..

Even with the set up, I have seen some issues with durability with long-term use of the Roush, since the brick is under the blower and could wear other internal parts over-time aside of the tune?

Some of the consensus I found based on the carb tunes is Edelbrock has issues of no engine braking and some surging etc.

@Mustangpursuit what issues are you referring to? Seems to me that cat failures are most common followed by fuel pumps. But I’d like to point out that even with those two failures the engines still live, which can’t be said about other tunes.

I’m pretty sure Roush designed it to not interfere with anything in the valley.

I’ve looked pretty hard at the edelbrock tune and it isn’t great. It is one of the few that use a stock os to build on, which does have an advantage if uou self-tune. The throttle body model is way off and the ipc error range is grossly modified to allow for the bad tb model. They also disabled some protections, which I obviously don’t agree with. The edelbrock tune is also really hard on the cats.

saw a complaint about a valley coolant leaks with the roush brick etc.

Wonder about Whipple canned tunes? a Super Snake (whipple carb eo stage 2) had a radiator hose blow out.

only mod I have to exhaust is just a borla touring cat-back. and my car has 3:15 gears with A10

As I said, the gen3 Whipple tune isn’t great. Kindof a mess really. Not sure about the 2024 but I suspect it’s more like the Roush since it’s sold through FP and ford had to sign off on the tune.

I currently own both the Roush and Whipple kits and really haven’t had any mechanical issues with either kit. Whipple kit issues seem to be more prevalent though, but it’s capable of more power.

I run what's in my signature with no issues. Close to 500 miles with the supercharger installed. Procharger tune. Everything works like stock, but more fun.

I know whipple has more power 800+ etc, but I see posts of people who have it say it drives more like stock till around 3K RPM then does some big kick, while Roush starts earlier?

Many all talk about losing traction, tires spinning etc, Is this all just attempting WOT during acceleration or pulls etc? With these systems, If I just gradually press the pedal slightly, I can maintain stock livability at all speeds even with All-Seasons.

The Roush 2650 is a smaller blower spinning faster than the Whipple, so it does generate a little more low-rpm boost and torque. But honestly it's not a dramatic difference.

Both Whipple and Roush manage the transition on to boost when the bypass valve closes pretty well. I've been told that the aftermarket calibrations that are based on stock OSIDs can "turn on like a lightswitch". By no means do these things respond like an old 2-stroke dirt bike. However, when you're trying to put 600-650 ftlb of torque to the ground in a 2wd car on all-seasons...well...it's not going to happen. In a stock kit, 1st and 2nd are never going to hook. 3rd can be sketchy regardless of the shape of the torque curve. When I was on the stock kit, the PS4S would generally hook in 3rd but they were 275 width summer tires.

That torque you talk of is attempting close to WOT correct? if I just let the car roll off a stop light with foot not on peddle and just slightly press down partially, It will drive like stock on All Seasons and still use all usable gears on an A10 driving normally, or I am underestimating the PD behavior?

If you couldn’t pull away from a stop safely then they wouldn’t be able to sell the kits.

Not exactly apples to apples but I have a Whipple kit on a 2013 Boss 302 and Procharger on my 2022 Mach 1. I Like the tune on the Procharger kit a lot better. Very smooth and one minor issue with rev match being turned off which Procharger fixed. The Whipple tune on my Boss has an annoying pop during part throttle shifts due to unburnt fuel. Sent Whipple a data log and they said it was normal. The car does pass Colorado emissions and makes good power so not too many complaints and maybe Whipple's tune on the S550s is better.
