I have a new to me 05 SRT-4 that has been modified a little. Who is recommended in the MA North Shore area that is familiar with DTEC? my car has a stock turbo, but FM wga and a larger intercooler. It also has a Needswings downpipe.
It seems to run ok, but I would like to make sure...I bought it used and do not know who set it up.
if you're looking to tune your car on the street or up at the track then you'll need a wideband ... plus it's a good idea to have in the car for diagnostic purposes
if you want to avoid buying a wideband then you'll have to dyno tune your car
It sounds like I don't have it. I thought that was the purpose of the DTEC FC/BC. Because of that, I have not paid as much attention to all of the wideband info. How much are they?
This car is also stage 1 if that makes any difference.
stage 1 is just a new pcm that will help you not throw codes, "hold boost between shifts", etc. ... only real benefit IMO is the fact it doesn't read the downstream o2 sensor so if you were to run a catless DP you wouldn't throw any codes
DTEC is what you would use to actually tune the car ... wideband is what you would use to watch the AFR's while tuning the car ... w/o the wideband you really can't tune the car unless you put it on a dyno ... a DTEC (or any piggyback) and a wideband go hand in hand
the cost of widebands varies ... there's some out there for ~$250 (aem uego, ngk afx, etc.) and there's some out there for ~$100 more than that (innovate lc-1) and then there's some out there for $500+ (zeitronix)
dyno tuning is definitely better than a street tune (which is what you'd do with a wideband) ... but a wideband is a better investment long term, especially if you plan on modding the car
if you dyno tune it with only a few mods now, but down the road decide you want to up the boost or add something new, then you'd have to re-tune the car ... if you don't have a wideband than you'd have to bring it to a dyno again
I'm on my 2nd ngk afx ... I sold my last one because I thought I was going to sell the car, so I parted everything out but then decided to keep it
I used to have the AEM uego ... I'm just not a fan of the fact that it's a 2 1/16" gauge (just like any other fuel pressure, oil pressure, boost gauge, etc.) ... I'd rather have a box than a round gauge - just personal preference ... also, the AEM uego doesn't go down below 10:1 AFR while most others go to 9:1 - not that you'd want to be running AFR's in the 9's but it's good to know exactly what you're running opposed to seeing " - - - "
I also used to have the TurboXS tuner box which is made specifically for the DTEC ... it's a little more pricey than the AEM or NGK gauge (about $400-450 for it) but it works great and looks great
also, keep in mind that you can hook the wideband up to the DTEC and datalog which will make tuning a breeze
I've never tuned on the dyno ... as a matter of fact I've never even dyno'd my car ... I'd rather spend the dyno money to go to the track ... I'd much rather see what the car WILL do, rather than what it COULD do ... although, I'm in a predicament now, because I'm probably gonna have to throw my car on a dyno to tune my cams

shoot me a pm when you're ready to go & we'll figure something out ... I'm having a meet at my house on Saturday Sept. 13th if you're interested - we could possibly do it then
you'll want to remove the sensor from the downpipe every now & then and calibrate it, which only takes a few minutes to do... it will ensure that you're getting accurate readings
