Not the issue. I am really surprised that people are saying they'd pay $500-750 to get from a respectable number, for a less than 10% gain. I spent $4000+ for a 75% gain. That's about $20 per HP. Those were guaranteed gains.

I guess $750 is still under $30 a HP. to me it's diminishing returns, but I guess not crazy.

$30 a hp if you get the hp.
You could get 10 hp.
That would be $75 per hp.
You could get 1 hp, that's $750 per hp.

Odd you think increasing HP by 30 more would be about bragging. $750 for 30 HP is alright, the tuner is a joke though.

If I remember correctly your motor is a 350? And the main mods are superram/brodix 180cc, and the lpe 219 cam?

If that is the case, I would be suprised if you made 430chp. I think that combo would be hard pressed to make 455chp with a well tuned miniram. 430chp is alot of power from the mods that you decided to go with. It's still the stock stroke. Get the tune as close as you can get it, and be happy with it. Did you see the latest Engine Masters magazine? They tested the AFR's on a 357 cubic inch motor.

$750 for a chip?

Gotcha. I don't know what his "magic" is, could be a tuenup and a tune....but that wasn't my point.

I am learning, like I said, that I'm in the minority. I wouldn't pay the extra for the 30 extra HP. Why? It's not guaranteed,it's a max number.

Well, that's the point. I didn't say it was a chip, nor did he. I don't know what it was, but that's not the point. What's the difference how he gets there. The point is 30HP max for $750. Bottom line. The mechanism is not relevant..

To my point. $750 for an unknown quantity that can yield MAX 30HP.

I don't know, it's not money I'm spending.

As to the 430, that's what the guys at Lingenfelter and Accel told me. I'm suspect too. Like I said. 330ish at the wheels, I'm happy. That's about 400 and change CHP assuming a 20% loss.

Ask him questions then, not us. You are stuck doing mail order tunes, unless there is a dyno close to you, and someone who can burn the chips on the spot.

What's wrong with my question? If someone cliams they have some magic recipe that MAY give me 7% extra HP, would you do it.

What's wrong with that question. I've already made up my mind, I'm not dealing with this guy for a number of reasons.

I'm just wonderin' what the rest of the world thinks. What's the problem with that? It seems the rest of the world and I are out of step. Most people would pay $500-750, I wouldn't I'm in the minority.

Besides, no one is forcing you to answer.

Yes not knowing for sure if the tuner would be able to make more HP would be a bother. But they usually do find a bunch of HP. I like more HP but I also think that a well tuned system will benefit in MPG and possibly not ruin parts like cats, sensors, etc. Just a thought.

Nothing wrong with the question. Maybe I missed it, but I didnt see the guys name or what business if any that he worked for.

i say who cares.

color me stupid, but if happiness is tied to numbers, ink and paper, then i'm out that door. numbers are for hobbyists and pretend hobbyists. if it doesn't kick you in the butt, then there's no point. you can be in a 400hp car and it can feel slower than a 325hp car. so what's so great about the numbers, they're for chest-slappers and blowhards. objective, subjective, i'll take subjective if objective is slower.

by the way, i never bothered dynoing my car over the past 2 1/2 yrs. i'm not spending $$ on it and absolutely couldn't possibly care less.

I had PCM for less do my chip. He's well respected. I'm going to run a datalog after I get the exhaust finished up, hopefully this week weather permitting, the datalog will tell me everything I need to know.

I spoke to Alvin and he'll make the adjustments on the chip based on the Datalog.

I don't see how I can get a better tune. Isn't this exactly what a dyno tune is? Run it, log it, adjust it.

Anyway, I still feel that money for that gain at this point, is worthless.

Again, I'm in the minority. I would go $250 I guess, but not much more.

Yeah but you dont like cars. Of course you wouldnt care.

jsup. The only better way to tune it is a stand alone DFI.

Good point. The dyno run for me will just be personal satisfaction. It will go in the file with all the other money I spent and never be heard from again.

I have a "before" I want and "after" just to measure my work. See, part of the dyno result is part of the hobby, to validate my on paper research.

Well, I'm going to put the header back on my car and see what I can do about the last leaking VC.......I got some really cool spacers made up for the AC compressor, I'm going to put them in too.

It's pouring rain so I probably won't get to drive it today to see how it runs with the new O2 sensor...

alvin tuned mine, and after 1 more iteration it was declared complete. he said "you now have a well-tuned car". that's good enough for me. his experience with live dyno tuning vs. his mail order resuts is very little to almost none.

so in my case, i don't need to care or worry about it.
