I was just wondering how important it is to get PCM retuned after putting in a stall converter because I am getting a nelson tune very soon but I don't plan on doing the converter for a little while yet. Anybody have any input on this?

 

Allen will upgrade your tune for free (-shipping) when you get your stall. You will definitely want a retune once you get the new converter.

 

that's cool, thanks for the info i would just wait but the more that i read how badass a nelson tune is i am getting to anxious, from what everybody says on here sounds like Allen really knows his ****.

 

Yeah, definitely need a re-tune after the stall. I just did mine this weekend shift kit, servo, converter, and Allen met me up there and we did a bit of street tuning. Glad we did too, cause the shift points, upshifts and downshifts were way off after all the installs. Plus he tuned the hell outta my truck.

 

Not to hijack, but will a tune make a big difference with my intake/exhaust? Would I get an 89 tune if that's what I put in it?

 

Most if not all vehicles benefit from a tune. Factory tunes are conservative, which means they burn a little rich (to be safe and avoid detonation) but this also means that there is always some power left on the table that can be recovered by getting a tune. Most tuners do transmission tuning and remove some or all of the torque management that robs power, and the can change your shift points to higher RPM's. There is a lot that can be done to a stock vehicle. Some people would even say that your first mod should be a tune. With Allen it is a good deal because if you get his tune on your stock vehicle and then make changes later, the updates are free.

 

i had a 3k stall for like six months before i ever had a tune so is not necessary although it would help out yes and i just went to allen yesterday and he rocks complete **** nicest guy ive ever had do anything to my truck two thumbs up

 

Klug, you might also check with some of the site sponsers about tuning. Texas Speed and MTI both offer tuning specifically for trucks. I know that Futral and Thunder also have some pretty bad *** cars and know what they are doing as well or better than anyone else.

As for a retune on a converter ... there isn't really much that *needs* to be done then. You might want to frm the shifts a little bit, but if that's done to start with, there's no need for a retune honestly.

Those of you who say there is, what are you saying needs to be changed?

 

I was wondering the same thing.

 

Yeah, I couldn't really figure that one out. I don't know alot about tuning but I wouldn't think that a different converter would change things that much. My buddy got his cam and tune from Texas Speed and his car is quicker than ****.
