is there anytype of tuning that i can do for my 05 sunfire its stock right now. i was wondering if the venom 400 is anygood or the hpt?
Venom is terrible.
hpt is good, but cant do much withotu supporting mods.
header, exhaust, intake, throttle body, cams, head, turbo, surpercharger

without a wideband you can change the factory stupid items. Those things that are set up stupid and serve no purpose like power enrichment being delayed till 6000rpm, and fans set too late to come on, speed and rev limiters
The major thing thats useful is spark advance, you can pick up some decent power and alot of gas mileage just tuning spark advance

so where can i buy one of these at and is it hard to tune it myself or does it just do it automatically? will this get rid of my speed and rev limiter too, because i will be buying the jbodyperformance head kit and the hahn turbo kit when it comes out so im confident it will be running over the limiter.
im confident you still wont be trapping over 108 in the 1/4 with the hahn kit and jbp head.

Well, when I ran my cavy with just the hahn stage 2 at 10 psi and trick fuel I went 13.99 at 106. So it is possible that that guy could trap 108 after all that work. Here is the vid to prove it.
