Increase hp

I was wondering if anybody would have an idea as to how beneficial it would be to remap my ecu? If its worth it, where would I get it done?

You can start off by simple bolt ons such as CAI, headers and exhaust. Maybe cams. I suggest a shark also little gains and also better throttle response. N/A motors are the same price if not more then a supercharger when all said and done.

i would say best bang for buck mods would be headers and a higher diff ratio and them maybe a shark even though people say A/F ratios are all messed up with headers and shark .

Ok, so I have been noticing this while I try to accelerate at a higher gear. I try to floor it and the acceleration is slow but as I am easing on the pedal I feel the acceleration. Has anyone had that problem? Hopefully I explained myself good enough.

They are equal length headers, which gives you a little more torque down low compared to other headers. Plus they are already coated. Great price. Plus they are discountinued. So get them while you can

you are trying to accelerate at higher gears, such as on the highway going 70mph in 5th gear or going 30mph in 5th gear?

They're not equal length.

A lot of people think that. I sent them to Burns to analyze when they built the Y-pipes for us. He said that equal length is good, but really hard to do at times. On these headers, the average length of the primaries works out almost perfectly.

They're just great headers. Made a ton of power and torque.

Swain coated to significantly reduce engine bay temps.

And they're rare! I'm actually surprised they haven't sold by now.

On the highway going 60mph in 5th gear or any speed going on 5th gear. Even if I down shift it still accelerates pretty slow.
