Default How Much

I want to get my 98Z28 m6 tuned and have a couple of questions. First question is how much does dyno tuning to get the must power usually cost on average? Second how much of a gin will I see from the stock ratings?

Here is a list of mods that will be done to the engine before the car gets tuned:
lid w k/n
gms maf
bellows
tb bypass mod
egr tube mod
ram air mod
160 stat
NX wet kit 75 shot
cutout

Im wondering what the numbers will go to without the spray. Right now The car only has the free mods and I'm guessing the rwhp is somewhere around 310-315.

Dyno tuning usually runs around 500 bucks total (depending on where you go)

With the ported MAF your gains from a tune are going to minimal. My guess would be the most you will get is 10 HP off the juice.

On the juice you could gain anywhere from nothing to 50HP depending on how you have jetted.

From stock I will only gain about 10 hp with tune and all the mods listed above!? That doesn't sound right. I mean the lid and k/n alone might give me that much.

Your tune is only going to get you 10 HP.

Your tune plus the rest of your mods........maybe 20, 25?

It depends on how good of a performer your stock car is. My 00 dynoed 270 from the factory. You never know until you slap it on the rollers.
