Hey guys,
I was thinking about getting the crawford plenum, 350EVO throttle body, and TS ECU. Now I already have an injen intake, no cats and Borla exhaust. Is it possible that with the plenum and the throttle body that my car will lose HP in the 1/4 mile. I figure that it will help my top end and MPH but at the line I think I might lose hp. What do you guys think? By the way my car already does 13.8 on stock tires.

not really..if your getting a reprogramed ecu you probably could ask them to richen your fuel and air mixture....but if its done wrong you might get a rich mixture check engine code. Or not sure if this would work but you might be able to get thru an adjustable fuel pressure regulator thru a couple of companies.....or one more thing you could get a Apexi SAFC that might help to program your air and fuel mixture, which you would connect this unit to your ecu...and a plus it looks cool at night.

From what I have been told..All you do is let Technosquare know what mods you have and they do a flash for those mod. And from dyno charts I have seen after the flash they get the A/F ratio to come out around 12.5 to 1 all the way through red line .

Couldnt afford it when young...gonna play when Im old

 

I'm curious steve, did you get your 13.858 1/4 mile at the track or using an accelerometer? I have never been at the track and thus can't figure out wat I currently have. My acceleromter tells me 14.1 and 102 mph, but I had that before the exhaust/RT cats mods. Don't you think my top speed is telling that my Gtech is wrong. It is unlikely to have a 102 traph speed but an ET time lower than yours is it?

I got the 13.8 at the track. It is very possible to get a slower 1/4 mile time and fast MPH. It all depends on where you make your most HP gains at. High, low or mid end. It seems to me you have more high end.

so in order for all the mods to give me their top HP I should have the TS ecu?
