Seems like quit a few mods,,wouldn't call a few items
light mods.
When I think of light mods I think of ,headers
it does not have headers...STOCK exhaust manifolds
Stock manifolds are good to begin with,they look like headers,no?.[/B]
exhaust
Also has STOCK cat back, and STOCK y-pipe with cat! replaced by Magnaflow resonators
Have not seen the stock sytem ,but is it all factory mandrel bent pipes?[/B]
cold air intake
No aftermarket cold air intake...just a RacePartSolutions air filter in the STOCK airbox
The SS is a performance SUV,so stock box is probably not too restrictive?[/B]
pulleys
Yup...its got a SLP underdrive pulley. However, they're only good for a few horsepower on a chassis dyno.
(I've got some aftermarket electric fans I'll be installing shortly...they'll give me an additional 10 - 15 rwhp!)
I think on those SS SUV's,the fan is controlled by the ecu? Could tweak that on off parameter?[/B] Not a big fan of electric fans.
larger mass airflow sensor
Nope...just a STOCK MAF; not even ported or de-screened
Stock I am sure is plenty big enough stock?[/B]
,,,along those lines,etc,that's maybe just my thoughts.
HP tunner is not inexpensive is it?
I burned $100 worth of HP Tuners credits on this truck
How much did the HP tuner cost initially,not $100
Converter pricey?
Moderately priced. Its the 258mm single disk billet, which is a little more expensive than the low budget re-stalled 6 cylinder converters, but still way cheaper than the multi-disk billets like I have in my Syclone.
What did it run best when it was mostly stock?
I'd say it is mostly stock right now. No headers, no cat-back, internally stock engine, internally stock tranny, stock gears, not lightened, stock wheels, stock suspension, stock intake and exhaust manifolds. no cold air kit, stock MAF (including screen).
Tunning alone is what helped it a lot & for most people,this is not a bolt on & go afair.Bone stock, my TBSS ran very close to what my Syclone ran bone stock (nearly 20 years ago).
FWIW, my Sy ran 13.8 the night I picked it up from the dealership
