Their Stage 4 is probably what I am going to do when I am ready.

I thought so myself.
When I am ready, I am also going to go with headers and catch can
My car is put up in my garage for winter now, a few more month's and I will be able to drive it again when the salt is off the roads

I agree...more like 8K at a minimum depending on what you decide to do.

Working with my shop...750hp is going to cost more like $11K but in addition to the parts/labor to get to 750HP (lower pulley, headers, plugs, tune), I am adding a full Borla S Type exhaust, Kooks green cats and Weapon X heat exchangers, LT5 ported TB and Catch Can.

Just my 2 cents...

Yea, that's right. A lot of people throw ridiculously low pricing out there with no apples to apples comparisons.

The major shops like those I listed are about the same. The variables include hauling and warranty.

There might be one or two people here that have a great shop or garage and could build an 850 flywheel for less but even they would need some help from others.

A very limited 3 year warranty just like the other shops

Whatever it costs, do it! Do you wanna be stuck with just 650hp and a slow car?????

Houston Performance Solutions
J- Rods shop
Matt Sorian (MS tuning)

For the record they all use Matt for tuning.

10-11k will get you to 750+whp
Ported SC
103 TB
Big Gulp
Headers
Plugs
Meth
Cam

Add about 5k to that to reach 800+whp. This is for the Mag 2650.

Obviously no warranty except for parts and labor maybe.

[JSH]

I'm skeptical about this all-in price, and I do not see it at their site. Plus, for me and most others, add $2500 hauling and $1000 dyno/tune.

LOL! I was going to ask how much you have driven the car? Do you find yourself holding it to the floor yelling "Come on Baby" often?

These things are beasts from the factory.

JSH, no offense but you already had your work done by HPE, and you are constantly trying to prove they are better and/or justifying the price you paid for the work and trying your best to prove no other shops can do the same for less money.

maggie will get you 700 rwhp supposedly.
7k if you install yourself.

FWIW it goes beyond the cost. When you mod, stuff may break, the possibility goes up as the mods and HP increase. So the reputation of the shop, their familiarity with what you want to build, do you know the guys who will turn the wrenches, have you met them,do they do a dyno or a dyno/street tune, what parts do they recommend and why...

High side gets dangerously low to achieve this. Typical is 660-680. At the high end injector pulse width can get almost to 6ms and high pressure nowhere near commanded.
