ok folks seems like you are all missing alot of my well documented data stock no stall no tune 11.9 at 116, then a tune in minus da 11.6 119.9mph dead hooking. Now i added a stall no more dead hooking and in warmer air and 800 positive da i ran 11.59 at 120mph. so for guys wondering about tunes and stall convertors here is my experiences and the times with the weather and traction all show a gain.

After those two posts, any question as to how much a tune adds? The 1 or 2 bone stock cars that ran 11.7 were factory freaks on perfect tracks with big negative da numbers.
I seriously dont think the tune added much to his times. Guys have hit 11.7s bone stock with DRs. An 11.4-11.5 wouldnt be a big deal at all with a good stall and a TCU that is tuned for it. Driver mod too of course.

Lol I dropped 4 tenths on my first run with a tune from OE. I had been running all day at a rental when I first bought the car. Jeremy from OE was there and sad he would put a tune on the car and let me make a few runs and see if I liked it. First run was .4 faster and every run after that was the same. Yes a tune makes you run faster. As for lsx cars of course a higher stall will help on a turbo car or centrifugal blower not to mention the stalls on those cars are 1700rpm. By the way this isn't my first time drag racing either

I'll just say I think you guys are wrong about how much gains you can get from a stall on any Auto car. All the fastest street driven autos have high stalls. I dont see why a Benz would be any different.

No not true. Hammerdown ran is 11.7 at Sac which has the worst track prep ever. It also doesnt have really low DA very often. I believe there are quite a few stockers with tires that have gone in the 11s.

Btw, I just noticed your sig says you're driving a 2015 E55. My bad, I have no idea how that car will respond to a stall converter.

The only way to really compare two runs is have the same DA and look at MPH. 4/10ths seems like an awful lot from a tune. Are these cars gaining over 50 WHP tune only ? Was that ECU only or TCU as well ? TCU I could see it. Also Jeremy from OE seems to be a very gifted tuner. I really need to get a custom dyno tune from him ASAP. I know I am leaving a LOT on the table...

Sac's rep about bad prep has long been proven wrong. Sac holds some of the records for quickest/fastest e55's known! I ran a stall in my first E55 so I know what they're worth. 1-1.5 tenths in the 60ft and 2-3 tenths MAX at the end of the track (if you're already launching to the car's potential).
Really its pretty damn bad most of the time. At least for Test and tune it is. I couldnt get my GTO to dead hook at all and it was only 450 WHP. With good DRs smoking burnouts and lots of runs I never did better then 1.85. You never see them spray VHT on it. Almost never sweep it. The left lane is consistently much much worse than the right lane every single time I have been there. 2-3 tenths may be all its good for but that is still quite a lot and enough to put an E55 into the mid 11 second range.
Did you like the stall on your E ? Pros and cons ?

I need a custom tune badly. I ordered a TCU tune from EC when they had that $250 special. Just waiting for the loaner to arrive. Cant wait to see how much it helps. My GTO when it was stock that mod dropped 3/10ths and gained 2-3 MPH with no other changes.

Pros:
-makes big pulley cars easier/smoother to drive on the street
-quicker 60ft/et's
Cons:
-TCU tune is a must. Some car's TCU will not understand how to interpret the difference and forget how to downshift on mild-moderate acceleration unless you go full throttle.
-3000rpms is overkill imho. These cars make max TQ by 2000rpms so with the lack of drive train upgrades, there's too much risk and not enough reward to stall above that (I've already twisted an axle and ruined a diff).

Mph went up 3-4mph. It's been awhile but I remember being stuck at 114mph stock that day (it's was in the high 70's) and the first run with the tune I went 117 and was so amazed I got lapped it a few times to see if it was a fluke and it wasn't. A tune is huge one these cars and ET wise on of the biggest gains you will see as far as mods go.

I'm guessing your GTO was on street tires? I had a 05 gto 6spd with bolt-ons running 11.60's then low 10's with a 440lsx with mozez heads. I seem to like drag racing heavy cars that aren't really the best for drag racing lol. IRS was a nightmare that I should of known better from my terminator days.

No was on DRs. Couldnt do better then a 1.85 60 foot. I had the smallest least efficient blower you can get, Maggie 112 along with shorty headers .
Bolts ons and weight reduction ? Those seem like amazing times for bolt ons. I know there are a few members with crazy times like that without many mods but there are very few. Most guys have decent sized cams to run mid 11s. My car could have run an 11.5 with a much better 60 foot but that would be about it. Damn low 10s all motor with a 440 or did you have a blower too ?

Out Of Control!!
Easy way to settle this. Measure how many times the traction light blinks before and after the mods lmao. If you want to go low 11s with a single mod put it on the bottle
