I pretty much have a bone stock car, or what I think is a bone stock car... the only thing i'm fully aware of is an aftermarket exhaust. I Just read that a tuning from Ion says 13rwhp is promised on a stock car... Plus I want to 86 the stupid skip shift option. Think its cost effective for a little extra power now, then another tuning once I do the headers, plugs, wires, etc...

 

cheaper then a cold air induction and will give more power then one also, definately worth it IMO

have the fan turn on temp lowered to 190*, skip shift elim, get the LT4 KM option or have him desensitize the stock KM, raise the rev limiter a few hundred rpm also, too maybe 63-6400rpm

plus pcm updates are cheap when future mods are done

 

His tuning is definately worth it. You can have him do a tune that will be good with the headers when you install them, so unless you need something else done then you only need it tuned 1 time. I felt a good gain, and the car shifts better and revs up a little higher.

 

I just got my tuning back in yesterday and it runs really nice. He did a great job.

 

if those are all the mods you plan on doing id definately get his tune....and any mods within 3 mo. tunes are free.....after that they are only 50 bucks. with my mods and his tuning i felt a huge difference.

and he gets it done fast.

 

He did my program and it runs GREAT.........I would definately say do it. He was also very,very,very good to deal with.

 

You think I should convert to OBD1? I was told I should, what are the differences? Pros/Cons? Power differential? I hear a tune in general will add some horse... about 13 or so... that true?

 

i highly recommend ion. he came through as always. my z is a beast at the top end now. with the many people on this board that have dealt with him and have positive comments, you know it's worth it. also have him program the fans to come on earlier (mine is 190 low-195 high). good luck

 

I have never heard anyone have anything negative to say about his service. I too plan on getting some tuning done soon.

 

Yep, 13RWHP on a stock motor. He told me that in an E-mail when i got mine done. Definately worth it.

 

Oh, definitely getting the tube, i'm talking about the conversion now. From OBDII to OBDI. I was told to get that. I was told that its just an easier computer to deal with on F-Bodies. Is that all?

Switching to OBD I will only gain a few HP. The main benifit is a dumber less picky ECM that is more tollerant to mods.

The problem is you have to pass emission in NJ. Switching your car to OBD I will cause you to fail.

 

When I got my computer reprogrammed, I decided not to put in for the higher octane. Was that a bad decision?

 

Higher octane would give you a few more hp. It just depends on if you want to pay extra for it or not. I would have gone for the higher octane deal myself.

 

Is it stupid to change to OBD1 though? Does anything change for my driving? I heard about some stall problems and whatnot... I just want to get the extra hp from the tune, I was just told to get the OBD1 Convert while i'm at it because of the extra power and its a better system.
