hey guys so i have an 06 ss/sc with the zzp stage 2 kit full gmpp exhaust zzp s1 h/e and zzp catted downpipe and a custom tune.right now iam making 248 whp but i want to make a little more power and iam not really sure how or where to start with this car.any help would be great

 

turrrrrbo swapskies

 

You could go turbo. And I have a nice turbo kit forsale lol

 

without going turbo should have put that in there

 

go 2.6 pulley e85 an meth but i would say dont waste your time on the m62

 

TVS swap
Methanol injection or E85

 

helps to know what sort of power your after. if its just a little more, dropping a pulley size, a better tune, alcohol injection, and other small things can add up. however if you want to make a bunch more power (300+) then a tvs swap, or turbo.

 

NAWWWZZZZ!!! Lol jk. This ^^^

 

Get a more free flowing exhaust, especially the header and downpipe. GMPP header doesn't gain much over stock

 

get a more agressive tune, lower pulley, and E85 or meth. with those mods you should be making higher than 248whp imo

 

2.6 e85 header and down pipe = 260 to 290 whp

 

Agreed...You should Def making more power with your current MOD's then 248whp, Get a More Agressive/Better Tune and Pulley Down to like a 2.7 or so.

 

What pulley size is zzp stage 2? I made 250whp Gm Stage 2 full boltons and ZZP S3 HE

 

2.9 i thought

 

You have a choice, it's probably a 3.0 or 2.9. I have S3 and am on a 2.9, but have a 2.7 ready to go on for spring and E haha.

 

I would go with a ported head, ZZP stage 1 cams, 78# valve springs, and nuetral balance shafts

 

Slightly overkill to go P&P head and cams, but if they wanted to spend 3k+ go for it. To make 40ish whp more or so just drop down to a 2.8 or 2.7 pulley with E-85 on 80's and have it retuned. A clutch at this point would not be a bad idea either.
