BLWR 993

I am seeking a tune for my essentially stock 2022 BGTS 4.0 6 speed.
I need assistance evaluating these modern plug and play engine modifications, as my experience is somewhat old-fashioned:
We rebuilt my '73 911E to 210HP 2.7RS specs so it shot flames out the exhaust, chipped my '84 Euro Carrera for a little extra scoot, and added Uni-Q to my TPS intercooled, supercharged '95 993 C4 for a claimed 410HP.
What I have learned so far regarding options for my 4 liter Boxster:
Softronic claims 440HP/346TQ for $1495. Reviews are positive, but performance increases are reported as subtle.
M-Engineering shows 369WHP/275TQ for $2495. They also offered me an additional 10-15 WHP with a custom hub-dyno tune for ~$1600 extra, if I sign a release. Reviews are generally excellent.
APR claims 459HP/347TQ on 93 AKI for $2500. They also report additional built-in engine safeguards and include a powertrain warranty similar to Porsche's. Reviews are generally excellent.
I need someone to help me cut through the marketing BS and choose a strong safe tune for my car.
I'm older now and not quite as crazy as I used to be, but I know Porsche left some easy HP on the table, and I feel this engine may have some significant juice left in it.
Any input is solicited and appreciated.
Thanks!

Save your money.

You won't get much tuning a NA engine.

Also, you should repost this in the right sub-forum here ---> https://rennlist.com/forums/718-gts-...niversary-255/

Warranty, what warranty ?

I did not think tunes were worth getting for N/A cars. Turbo cars on the other hand, sure...but not N/A.

I plan on going with APR. i've used them in the past and was very pleased.

There are lengthy technical discussion threads on all the 4.0 tunes you referenced in the 4.0 sub-forum.

Read those existing threads, bump if you still have questions.
