He is remapping my engine spark and fuel maps for optimum performance and changing the shift points to my specs. I chose 6000 RPM as my preferred shift point at WOT because at 5200 RPM my car feels very strong and wants to go further but the da*n GM ecu wont let it shift past 5200. The intake on my car is also different than yours being it has 3.5" piping so as to flow higher at higher RPM. Also I believe there is a slightly different supercharger from 93 to the 95 model, which could contribute to a slightly higher upper end RPM flow. I also chose 6000 RPM for my shift points becuase thats where the general set the redline in the first place, heck if I can go past the yellow with my boost gauge how come I cant with the tach?? ( )

I do not have ready access to a dyno chassis or otherwise, and have learned not to trust my GTech for I have the older GTech performance pro meter, and it seems to estimate low horsepower when I run it. I do plan on getting a chassis dyno done within this summer to truly determine what is going on with my motor.

It'* your car do what you like I'm just saying that that high of a shift point is not wise for your current level of mods. Your performance and reliability will suffer.

I tell ya what when the new ECU shows up ill go to the track and see what I come up with Ill try the current ECU which has remapped fuel and spark with the factory shift points then Ill toss in the one with higher points and see what I get. If your right beers are on me, if im right you have to let me drive the 8 ball (yeah right)

Besides that I dont plan on drivning my car at WOT all the time, mostly only when at the track or if im really trying to keep up with some of my fast car buddies.

Your chip programmer doesn't have all the info that he needs. It'* not a plug/play science. You need dyno time BEFORE the chip is burned. Period.

6000 rpm'* is ridiculous. Your power curves don't go anywhere near that high, and actually start dropping off at least 1500 rpm'* lower than that. You just bought a 'slow' chip. In addition to all that, your 3.5" intake won't flow any better than mine, and in fact, mine will work more efficiently. Your car is nowhere near modded to the extent as other L67'* here, and they can't outflow their 3" intakes. Because my air is at a higher velocity, it tends to have less turbulence than yours, insuring a more accurate MAF reading. 3" pipes have been dyno'd to produce more hp than 3.5" by ADTR.

Do NOT shift at REDLINE! That'* more wrong than you can possibly imagine. You WILL destroy your car. It'* only a matter of time now.

It doesn't work that way. The Eprom swap must allow time for the PCM to adjust and learn. This typically takes up to 100 miles before it'* ready to perform at it'* best. You simply can't do back to back runs with different Eproms.

unless you upgrade your valvetrain those 6k rpm shifts will KILL you. You wil have valve float like crazy.

By the way my chip programmer obviosely knows more than you think because the first chip he sent me still has the factory shift points, which is the one in my car now. He is also sending me one with a 6000 rpm shift point at my request. Hes just doing what im asking...if anyones ignorent here its not him. Also does anyone know where I can get a mild performance cam and roller rockers and higher strength valve springs?

First of all, nobody here needs to chill out. We're warning you about blowing your car up and wasting money on a bad burn.

Secondly, your chip programmer doesn't know his arse from a hole in the ground if he'* burning a chip without your dyno numbers in his hand. How he'* taking your verbal request for shift points is the most ridiculous thing I've ever heard of. Fire him as soon as possible, and find someone with a good reputation, and an analytical approach.

(not busting on you, but I call 'em like I see 'em)

The major chip-tuners in the aftermarket world will NOT touch a burn until they have all this information. Without the knowledge of when the hp and tq peak, you can't burn a chip. Period. You have to know this to determine the shift points.

You already have roller rockers, and you'll need to have the cam custom-ground.

Aight sumbody needs a hug LOL All I meant by chill out was not to worry about it right now were looking at a year before any of this actually gets done to my car. Thank you for youre oppinion about my chip programmer, but I am very happy with his service and the chip he has burned for me has EXTREMELY good drivability. (i.e. the way it FEELS)

I will get dyno numbers and have them posted before the end of the month so we can all see what a SER1 can do without resulting to major mods, then I will look into a custom ground cam and heavier valve springs and maby replacing some valvetrain componants (for reliabilitys sake).....ive also been wanting to replace my injectors (again for reliability sake) By next year it should be a farely meeeen machiiiine.
