Well after my new headers and exhaust i had to get my tune retuned but could never get ahold of charlie wheatley so i ordered a new mail order tune from allen nelson. I ordered it friday cant wait until it gets in to see the different between the two.

 

Definately keep us posted. Maybe you could make a video so I have something to go by in comparison to mine.

 

i have a nelson mail order tune an love it!!
a live tune would definitely be better, but for what i have done to my truck its pretty quick and could definitely tell a huge difference as soon as i plugged the ECM in.

 

How much does Nelson Performance get for a tuned ECU? Is there setup where they send you one and you pay the corecharge and then send them back your old one for your core money back? I might be getting a custome tune done after I sell my Supra depending on how much spending money I'm left with after moving to Tennessee and getting settled in.

 

The tune was $375 with a $55 core because i cant send them my old one back because its locked from wheatley. And then $10 shipping. So all togather it was $440.

 

where is the pcm located, im thinking of getting a tune from nelson and wasnt sure where to remove the pcm from?

thanks

 

Right next to your battery under the hood you will see the two wireing harness going to it.

 

cool. i will look at it later today. is it fairly easy to remove?

also what kind of tune did you go with? im thinking of a dual 87/89 octane tune they offer with their recommended Torque management of 70-80% removed.
im not really looking for top end, just a little better towing. the factory 3.42 gears arekilling me.

good luck with the tune. when should it be in?

 

ok, so i looked at lunch today. is the pcm mounted on the firewall by three studs and nuts, black in color, with the two plugs coming out of it?

i have a "brace" overtop of that area connecting the fender to the cab.

 

Nope. Pop your hood and on your driver's side, between the grille and the driver's side headlight, there is a black box mounted at an angle, next to your red terminal box. It is about 8" x 8" and about 4" thick.
