No their not related, but two things. One, my car was seeming a little sluggish. Almost like a dirty air cleaner even tho they are relatively new. It's been a while, so I bought some Techron additive. Immediately the cars performance improved. I mean alot and within a few miles!! Think there was something blocking an injector?

Also, I'm curious about hearing from those who did the ECU upgrade. 15 ponies for $500.00. Do you really see much of a difference from 15 horsepower? I read somewhere you can expect maybe a 5-6 HP gain with K&N filters. I did feel a slight improvement, in the low end, but if thats 5-6HP, what do you actually get from the 15 HP of the ECU re flash?

By the way, 4 years, over 40k miles including winter driving, and the paint still looks like new. Best paint job I've ever seen on any car.

 

It's really noticeable from about 3K RPM and up.

 

Autozone had techron on sale, buy 1 get 1 free.... So I added those 2 small bottles into a full tank of gas.... And as far as an ecu upgrade along with the intake....A huge difference with the SRT-6, and probably a worth while increase in the n/a with the way it affects the entire rpm range. If you know someone with an ecu upgrade, test drive their car and see for yourself.

 

ECU tune really helps, and is more prominent with other mods -- add the CAI and exhaust, it all pulls together pretty good.......

 

fuel filter time

 

throttle reset will improve your performance, cost, nothing....try it...
