HP increase without a tune?
Hey guys,
Considering I just spent a bunch on a new tune 2 months ago I am looking into what upgrades to do to increase RWHP without a tune. Is that even possible? Some things I have been looking into: electric water pump aluminium drive shaft headers off road or high flow X pipe S/C vacuum upgrade (more effiency than HP increase) Any ideas or suggestions? It would be GREAT if I could add on another 30+ hp without a tune.

Id say headers
When they did your tune did they turn off the rear 02's? If not your gonna throw trouble codes, Also if you have a wideband you can make sure a/f's are still inline after you instal headers (shamless plug) As a matter of fact I have a set f/s right now too JBA long tubes w/ non catted H-pipe

Besides the drive shaft.........dont forget you can also change out the fly wheel. All of it evolves around less mass that has to be spun,and that equates to more horse power to the rear tires. speaking of rear tires. If you have the 20" X 10" wheels you can also go with the smaller 20" X 9". I know it sounds like im nit picking, but every little bit does help

Anyone have any experience with the electric pump? I have heard both sides of the story. Reliability seems to be the key issue. I like the idea of the pump being on a t-stat. Especially taking it to the track and allowing the pump to run to help keep the engine cool while waiting for my turn.
Thoughts?
