Finally got one

[ThunderMelon]

Thanks for letting me join! I picked up a 2023 5BW recently from a guy who upgraded to a 2026. Absolutely love this car and was lucky to find one I could afford. I took a risk because it’s already modded heavily so the warranty for the powertrain is void. The win, is that Scott from Tapout did the work and I’ve learned to trust his shop after years of researching before I purchased. Had to sacrifice a few things: wanted black and wanted an M6. Got red and A10, but the car is super solid and I only paid 80k. Too good to be true but it is!

Very nice! I wonder how much they spent on all that modding? Getting the car including the mods that got it an additional 200+hp for only $80k is a steal! I know I am in the minority, but I think that much extra power is better paired with the Automatic over the Manual. I think it will be way too easy to go sideways (when you don't want to) with a manual.

The post says it is still running on factory injectors. I do not know how that is possible with that much more boost and running on E, even if it is E60 instead of E85-E90. Are you pretty sure they are still the factory injectors?

I have a 2nd Gen CTS-V @ 804whp and I have almost 3x the flow of the factory injectors. I know the setup is different on the LT4, but I am still really curious.

I definitely scored with this car for sure! I had a deal secured on a black M6 with 14k miles for 97k that was all stock and then stumbled on this one. The dealer broke the black one before I could pick it up and the red A10 was a gift from above!

Luckily Tapout did the tuning and work. I really respect their shop and felt confident on the purchase bc of that considering warranty is gone. Hopefully there are years of smiles per gallon without issues.

After speaking with Sam the original owner, he installed 30% over injectors when he did the DSX ported lid and LMP heat exchanger. Other mods to the car are a savage Cadillac carbon steering wheel(looks killer), Katec oil pump, DSX flex fuel kit and Aux fuel pump, ARP studs and bolts throughout, LS7 lifters and tray for DOD delete, PD3 cam, the intake and Kooks long tubes with green cats.

I did a rip today and the boost gage showed 16psi as I white knuckled my way to triple digits. This car is an absolute menace even with the 325mm Michelin PS Cup 2’s out back. Couldn’t be happier with the power and shout out to Scott at Tapout tuning for a professional install and clean build all around.

That car sounds like a beast! I'm not one to mod like that, but I think what you paid is a good deal.

850+ hp is 850 hp, sideways will happen regardless of transmission. Definitely going to be faster with the 10A. I'm all about the 6M, but I had the 10A at Spring Mountain and it's a great transmission.

It definitely seems like it is perfect as is. I would not make any changes. You can still have a lot of fun with that on the street. If you get too much horsepower, it takes away the fun becuase you can never "put your foot down" without losing it. I am not sure how many fast cars you have had in the past, but I would recommend trying to learn the car in safe places. If you are not used to that much power, you need to learn how it works with your individual driving style before going too heavy on the streets. I have seen too many people wreck because they did not try to learn the car in places away from other drivers.

Yes, that car can go sideways and do donuts no matter what. I just mean the shifts will be a little smoother with the A10, so it has a little less chance to go sideways at higher speeds. I have an auto myself because I originally wanted it as a daily driver with a goal of drag racing. When I line up against another driver at the 1/8 & 1/4 and they have a manual, I know I have the advantage. Now, road racing is a different story so you want the 6M.

Definitely not looking to add anymore power. The car has plenty already. I’m just going to smooth out the shifting ergonomics with a transmission tune shortly and then leave it be. Been taking my time learning it like you said. I fly helicopters for a living so I know all about respecting a machine. I just can’t believe how perfect all around this car is. In soft or firm settings, it’s perfect. Well done GM!
