with chip will work best with my 94 ssei I will be changing the pulley and intake and cat and cat back

I'll vouch for the Jet for sure. Works great in my SSEi, and it'* actually been getting stronger in the week I've been running it as the PCM 'learns'. Do your intake, exhuast, and 180° Thermostat FIRST, as the Jet Stage 2 chip is tuned for those mods. I ordered mine from Hector. Great price. Allmachtige just ordered his and hasn't got it yet, and Turtle is also running it. Has been for quite some time. Allmachtige is running the Superchip currently, but is changing, so he'll be able to give us a direct comparison between the two. The superchip is a full swap, and the Jet is a piggyback.

As far as your intake goes, I should know this weekend if the ADTR intake fits a Series 1. If it does, you're in business.

We must have been typing at the same time I beat you to the submit button!
JR, you really gotta get this chip.....after Allmachtige tests it. I'd love to see what it does in a Series 2 NA.

How do you get a chip? Easy. And only one word.

Hector.

Will you keep saying the Jet chip is a piggy back chip. Does thing mean I would still use my superchip and piggyback the Jet chip? Or is it an Eprom swap?

U confuse me old man!

Your Superchip is a swap. The JET is a piggback module. Modifies the inputs and outputs to and from the OEM Eprom. DO NOT PIGGYBACK your Superchip. I've never heard of this, and it could only be bad. I hope you have your OEM eprom still?

If you have questions or want to get a Jet chip contact me at the email address below in my signature.

No dont worry Will, I still got my stock eprom....SOMEWHERE in my dusty garage :P
I'll worry about digging frantically for it when my Jet Chip comes.

Does Jet Chip make one for an 1989 3800? can you use a newer chip in an older model? if so what are the best for older years?
Thanks! appreciate any info as want to order new one for spring

Ok the Jet STG 2 chippy works like a hot damn..on Series 2 NA 3800......i have one and if perks everything up from shifting to fuel curve.REMOVES TOPEND GOVERNER.. witch ( lol ) most guys/gals will like, the Stg 2 likes the mods Will said to do ...i have a wee bit more mods and my JetStg 2 likes these even more........
