there's ways to tune traction problems

most of the fast vehicles don't even want to race from a dig anyway, they bitch about not having traction.

try asking one of the vendors on here for the valve the could save u a few dollars

I originally wanted to end up spending about 6000+ within the next 2-2&1/2 years to get some crazy power outta my truck. but now that i have a 2wd it seems like it may be pointless since the more power i get the more weight i'll have to put in the back to race... And i may end up going with getting all of it and just asking everyone for money for chirstmas. All of it as in wheels, tires, gauges, PPE, exhaust. And i may order in the boost increase valve tomorrow

exhaust and gauges may come in pretty soon too.
oh and i forgot to ask. if i do decide to get way up there in power should i wait to get the 5" exhaust since it's gonna be a couple years.... and is yours dual?
mine is 5 inch single.

5 inch exhaust helps more with a bigger turbo, 4 inch is good cause it costs less, and adds more hp than a 5 inch exhaust would to on a stock turbo.

haha yeah i hate it too. but of course when you are on the road it usually keeps speeds down. And i can't really get another ticket right now... i've gotten puilled over twice 97 in a 55.... got off both times but i dont think the 3rd time will be a charm.

But i have noticed that i blow people away at a 30 roll like you said.(atleast i think it was you..) and yeah i was actually about to go post about the increase valve

---AutoMerged DoublePost---

AH! another thing. my truck kinda stuck at 50 the other day while i was hammering on it. what was that about? like it kinda feels likt it stick sometimes...

sometimes the transmission can pick up bad habits. its always adapting to the way you drive. and adjusts itself to you, its always learning

Ummm...Yeah, that doesn't sound creepy at all
But it's pretty sweet at the same time.
Any other cheap easy mods like the increase valve?

i know a cheaper mod than the boost valve, but its dangerous with out boost gauge, could blow up the turbo

mod the intake, shave the antenna, all headlights on mod. all of those can be done for less than $20 combined

engine has too much electrical stuff on there to get cheap hp out of it. needs programming

---AutoMerged DoublePost---

But what is headlights on mod? and i saw the shaved antenna thing and your intake box mod. but i'd have to read back over it to do it.

if you do 5 or 7 litte $100 mods that adds up to a programmer that could have been bought.

theres a few more, but you wont see benefits untill you start adding tons of fuel and air to the engine

unfortunately there still isnt a write up on how to to the all headlight mod for 03+ gm trucks. Hint Hint

it keeps your low beams from turning off when you flick on the high beams

But heres a simple pic of how to wire the silicon diodes needed for the modification.

very true. I' may just stick with the boost valve and any other little things that would be like eating a meal at home instead of going out to eat. ( i eat out alot but have started too cut down to save $$$) But i got a good deal on the programmer i want from here so hopefully that will be a late november buy then wheels and tires for chirstmas.

---AutoMerged DoublePost---

an yeah definately not gonna try the headlight deal. I'm thinkin of getting HID's anyways.
