Ive been looking and which chip is beter for a lightly moded l98 including a cam that i think has to much duration for the ecm ,intake work,porting, and exhaust.
What im having a problem is at idle with the car in drive the old chip keeps trying to lean out the car to much and the cam does not agree with that and it results in alot of surging and a few stalls.
I have the option between a stage 1 or 2 id like a little more power and will these chips constantly lean out the car making it surge?
Also will these chips require higher than 91 octane? because that will get expensive fast

 

You need to get a custom tuned chip for a aftermarket cam. A jet or hyper chip is not programed for larger cam. All they do is add timing at wide open throttle. Here is a good guy to contact. http://tbichips.com/

 

what im asking is my cam is just borderline for the stock ecm and will these chips at least agree with it better so that it does not surge as much or go to the lean side as much during driving?

 

Answer to question is you may not know till you drop it in ECU. If you do not want to burn chips for max power and drivability then you need to consider aftermarket as you are doing. I suspect they will improve over your stock tune. But it is mail order and mail order is always a compromise. contact Jet and TPIchips.com and ask if they will communicate with you through your datalogs you do(your minmum effort) to maximize their efforts on a series of chips(burns) getting in right. Read up on datalogs. One chip try by them is unlikely to be "good enough". But better than stock. With the price of gas at $4.99 you need to get that tune right.

 

If your going to spend money on a jet chip to only find out it does nothing but WOT timing, I would call Brian and talk to him about a custom tune for your cam. It wont cost any more than a jet chip, probably less.

 

Sorry to say red rock, but a Jet chip does more than just add timing at WOT. I've got a stage one in my L03 Firebird and I've noticed a performance gain across the board. It also adjusted my shift points and when the torque converter locks up. Now the thing gets decent scratch on cement from a start.
I'm doing some mods (full MSD ignition & Trick flow heads) to hopefully add a bit more pep to it's step and eliminate the 305's oil burning issue. I'm curious to see if a stage two would help any.

 

With your 305, it will move the torque converter lock up from 25mph to 40 mph, but on a stock 350 the tc lock is already at 40mph. And as the op stated he has a lightly modded 350 with cam, which, for the best results would need a custom tuned chip, perferably on a dyno. I had a jet chip in my 350 when i got it, i took it out and run stock with no change in performance. I sold it for $100. As for your jet chip, good for you, maybe you got an exception, but there are many threads contradicting aftermarket chips.

 

I was thinking aftermaret cannot lean out A/F for fear of damaging the cat con. If a person has deleted the cat con then enleanment may benefit. Jet or any other burn for hire would need to know that up front.

 

I found this funny as I read this, I had the exact same result. For me both my 0-60 and 1/4 mile times showed no improvement, I had the stage 2 one made for people with a exhaust. To be fair there was a difference in the MAF scalers that made the car feel stronger in normal driving but it used up lot more gas, and only other change was 2* more timing in the upper rpm range, so yeah big waste of money. Hell I might even have that old Jet bin kicking around somewhere.

This is the reason I got into burning my own chips.

 

I agree with Tony, i use TP/RT i was able to compare my 92 L98 bin which is AUJP with a " Stage 2 " and as stated above there was only a few * of spark at WOT and a few very minor changes in the entire bin, Down load TP/RT for free go to Moates site and grab both the aujp bin and the stage 2 bin load them up and use TP/RT compare tool and you will see for your self. This is how i ended up burning my own bins....its easy and very adictive, hope this helps...GTA

 

If this hasn't been said already, the real difference is the $$ and what you're paying for premium gas. I sent my hypertech chip back because it actually made my car run worse.

 

how do you make your own chips? I have a stock v6 5spd. well intake only. but i want to pull more power out of the stock motor without completely screwing myself in mpg ..any help will be greatly appreciated...

 

Or how do you flash your chips(me)?
See stickies above.
see dynamicefi.com

 

Is that completely safe for my car? dont want to ruin or damage anything at all. Also, can one tune an ecm to get more power out of a stock v6? I know the v6 motor has more power to offer than facotry settings. without screwing myself in mpg. ..
Thanks

 

I got my chip from Brian and and he was always available for my questions etc. quick correspondence and very helpful.

 

Actually, the stock chip locked the converter at 40 mph and caused me to believe my trans was on it's way out based on how and when it shifted into other gears. I prefer sticks so being that I only drive the firebird 4 months out of the year the shifts just didn't seem right. I put the jet chip in and now the converter locks up around 35-37 mph which to me is great. The car doesn't lug and my foot is barely on the gas pedal, and so with 2.73's the car is basically idling down the road. Plus the other shifts are smoother and I can't feel them anymore. Also, depending on my speed the old chip would force it into 1st if I pushed down to far on the throttle. Well the lo3 doesn't make any power up high so I had to remember what position to avoid going past when at those speeds so it wouldn't downshift, it was actually faster that way. Now the chip holds 2nd just like I wished it would! I gotta add that I did the chip swap and edelbrock performer tbi manifold swap at the same time, so maybe the performance gains are based off of the manifold swap. Suffice to say I'm happy with this chip but if I ever swap out the cam and what not I'll be looking to have someone custom make a chip for my car.
