We've had a couple of those installed here. Fastchips hasn't impressed anyone in a Bonneville yet.

give me a little more time, i havent been able to get the car out and really drive it because i have been having problems with the battery since i installed it last week (replaced under warrenty last night) As for a so far reveiw, I think the car is pulling a little harder and smoother then it was before, but i want to put more then the 30 or so KM on then i have already (I think ill take the long way home tomorrow (highway ))

I know there is also a superchip option, but I haven't heard rave reviews about that either. Do you think with some scan tool information gmtuners would be able to do the same for a lot less?

Since the 92-93 L67 crowd already have a dyno tested chip I would say no for them. But for other applications you can still get great results catered specifically to your car/mods/climate with gmtuners. It does take a good amount of data logging and a couple tries. (which dosen't drive up the cost.)

ok well this is what i have to say, from what i can tell from the scans i have made, my KR is down by half at its highest spike (7*) and stays around 3-4 when the RPMs get up high before it shifts, like i said before the butt dyno feels slight improvment, but i think my car is still being by its bad EM'* and i think that problem i have been having is still there but ever so slight, so i dont know if it was worth the $300+cnd (customs killed me ) in my current condition so im hoping it will come alive when i get the EM'* fixed up

Just remember your KR will go up when summer comes around again. Get those EM'* fixed before then, and if your fuel pressure is good, you should be in good shape.

well i dont know how accurate it is, but he scan tool said RICH durring all my WOT driving, but then again it only says rich or lean so who knows how rich /lean the car might be when it says one or the other

thats just the O2 sensor trying to keep a 14.7 air fuel ratio. You need to look at the STFT or LTFT also your fuel pressure should be checked (I thoght I read a post that you changed your fuel pump?). Also did you change your FPR also?

? STFT or LTFT ?

and no the GPR was not touched, just the pump sender and tank

short term and long term fuel trims
