Has anyone bought a chip from http://www.PerformanceResource.com ? They claim .6 off the 1/4 time on a stock TPI . Chip cost $230.95 ... AJ

 

I would go with Ed Wright of FASTCHIP for a better company and reputation, and also they are cheaper. A happy user of this product. Also its good policy to discount 80% of what a MFG claims his product will do for you.

 

I'd go with www.fasterproms.com and did. AFAIK, Ed Wright does not do a custom chip unless you go to his facility and buy some dyno time.

Fasterproms will send you a chip to your specs and you tell them what you would like changed in the open loop area and take Diacom readings for the closed loop areas (WOT, Curise, Idle). From these readings they burn you a chip and you do the readings again. If all is well, you pay $500 and if not, they keep at it till it gets on the money. That way, it is truely customed to you.

In the future, when you do some heavy mods like different cam, heads, intakes, etc, it costs you $150 to repeat the same sequence.

This will ensure that they will burn you a chip that is customed to your car istead of a guess. This eliminates the dyno because you will be running your car on the road to get the readings. Also, there is no downtime as you don't return the chip till the new one comes along. Usually done within a month without you having to leave town for a dyno run.

 

I burn my own.... With 1 yes ONE single burn I gained .7 and 5mph and the car still runs rich up top and is a pain in the *** to drive. Cost me a couple hundred for the setup.

 

Did you swap to different injectors? Unless your timing was way off I can't imagine a stock 22lb injectors with a stock 350 chips being that far off.

 

Since the original post asked a question about a relative stock chip. He did not ask to have a custom chip or burn his own for what sounds like a stock engine, I still recommernd the FASTCHIP .

Actually he does do custom chips. I believe the price is $350 for the first burn, and $150 for any additional burns if you change your setup. You just send him all the info on what your setup is. He's got a good rep, and a bad one, depending on who you talk to. I had him burn the chip for my 305, 355, and 383 setups. The 305 and 350 chips were pretty good, IMO, but the 383 chip he tuned was way off. I sent it back to him, along with some logged data, and it came back STILL in poor tune. Last Friday I took a little road trip to Tulsa, and had him dyno tune the car to correct the problem. The car is running awesome now, all tuning problems fixed, and durning the dyno tune, he managed to squeeze out an extra 23 hp and 12 ft/lb of torque. All this he did for free, just to correct the problem with the PROM. His customer service was awesome, I was really pleased that he was able to squeeze me in at such short notice.

 

When I had Fasterproms do my chip, it always came back ok, then better and best. Without logged data and burning it to the data, it is just a guess just like Fasterproms first burn. The second burn is with the data you logged and so is the third burn. The beauty of it was that I used the back road dyno to make it work without having to go all the way anywhere else.

 

My '92 Z-28 is stock 350 TPI , auto , 3.23 gears . I've added TB air foil , K/N air filters , Jet fan switch . In the coming months I will add TBBP , ported plenum , and free flowing muffler . Since the car is stock I don't think headers and pulley's will help me that much ... AJ > Patriot

 

I added a Superram setup and could feel a difference. Add headers and you can also feel the difference. Had LPE reconfigure a couple of things on my EPROM and there was a definate smoothness in the running. Felt better too.

I bet headers will help you a LOT. I picked up a full half a second when I put on my headers and high flow cat. No kidding! But then again, I had a single cat setup which has a much more restrictive y-pipe than yours, so you may not gain as much. But either way, headers are the way to go, I bet they'd help you more than anything. As for pullies, I've got a ton of stuff done to the Z, but I passed on them. I just hear too much stuff about them causing problems, and not enough stuff about getting more horsies from them. Just my .02.

 

I have the dual cat set up . So you think I should get the headers , huh ? SLP 1 5/8 or SLP 1 3/4 ? I want to get the most out of my car without going into it ... AJ
