Hello Folks,
Just got the Goat back after installation of SLP LT's, ported-polished intake- throttle body, 228/232 cam and tune, baseline and after. What a forking monster. I had no idea how mean she would be & sound. Around 500hp at the crank and 412hp at the rear, 388 RWT. Robert at Adanced Dyno did a super job. Total paid for parts and labor $3,725. She is a totally new and better GTO. Please excuse the crappy Pics. old camera...

Reason: Spelling
You gained 100 hp at the crank from those mods only? Slp has a 490hp pac that costs $5k and has alot more upgrades/parts than what you got. SLP Performance Parts - VIEW P/N: 29053 Why would the slp pac only add 90hp with so many mods when you were able to achieve the same results with less parts and money.

SLP has one interest only and that is selling stuff. Re-read my post. Porting & polishing are a big factor and offer zero money for after market company's. No money in it for them to upgrade stock compoents. Also, I had a few light Mods. in place before the latest work, so it's not a stock to 100-HP jump. SLP packages are not the necessarily the best way to go. The best route is a good local tuner with LS1-LS2-F-Body know-how. The preditor-tuner just does not cut it when it comes to gaining the Max HP.
My numbers are real, like it or not...

Hi,
Those torque numbers actually seem a little low.
I have an 05 with basic mods;
Pacesetter LTs with catless mids
X-pipe with glasspack muflers
K&N Drop-in filter
Dyno tune
I got 369RWHP and 367RWT
I am unable to split hairs over the packages offered and what is best. To new to this stuff. I'm learning much from you all though!
The pipes look awesome and with a cam to boot, it must sound awfully sweet.
Power I'm sure you can feel!
Very nice!

I wasn't doubting your numbers man. It was more like wondering why the slp pac cost so much more, adds more parts but nets the same gains as you did. Your mods def seem like a better option and value.

Hmm... Every motor is Dif. Maybe you have a stronger beast? The numbers are what they are... Nice #'s for your Mods.

Nice numbers [ are they corrected numbers ] but too bad it was on a DYNO JET, put it on a Mustang Dyno and get real world numbers. On a Mustang Dyno you will be more like 375 RWHP. The Dyno Jet always give higher reading because it is nothing more then a free wheeling system. It is a good tuning tool just not very accurate for HP & TQ readings.
