If I drop from 5th to 4th (or 4th to 3rd, the common demoninator seems to be the rpm's) and floor it, at around 4800rpm the car feels like I just got an extra gear or a mild power boost.

A friend of mine thinks due to my upgraded CAI and throttle body allowing more air, there isn't enough gas being pumped in down low. When the rpms hit a certain spot it dumps more fuel thus feeling like there is a power surge.

Should a tune even this out. It is quite a rush when it happens. I would like it to do that waaay sooner.

Thanks ahead of time for the response(s).

you sure you don't have a centrifugal blower on that thing? when mine hits boost around 3000-3500 it hits a power surge like that. i'd be willing to bet that a tune would even it out a bit. in general, a canned tune should add a little more spark advance and a better fuel map for your mods. plus, when (or if) you get gears you can reprogram your speedo without having to buy one of those calibrators.

With out dataloging whats going on its just a guess really. The CAI is messing with your transfer function that's for sure. Meaning your MAF is lying to the PCM as to how much AIR MASS its really seeing. This could cause a multitude of problems. If you have the stock air box slap it on and see what happens.
