Reason: Help !
You'll get lots of opinions on that question. I went with a 3800 stall/2.7 STR from midwest, and it's like a new car. Definitely a mod I should have done first. Converter, cooler, and transgo all in one time is the way to go. I also installed aftermarket billet servos at the same time. And by the way, the transgo isn't THAT hard to do by yourself - don't let the instructions intimidate ya!
That's not really an option man. You NEED to get a scan tool. I'll bet that you have some KR with your setup. You'll need a setup like LS1 edit to tune and get rid of the KR. Seems like most 98's have KR when they shouldn't. I know that mine did.
I would get a converter. Put the stock maf back on. My 98 has no KR even with the HPP3 tuning. 98's are less likely to go lean. They run richer from the factory than other years in most cases.IMO Aftermarket Maf's are a total wast of money...
Definitely a converter for the mod, but I agree that you need to make sure you aren't getting any knock retard too. Junk the GMAF and HPP3 and get a custom tune along with your converter. I personally like Yank Converters, but my car came with a Vigilante 3200 in it so that's going to stay in there for at least a little while. I'm looking at replacing it with the YPT4200 or SS4000. Give them a call with your car specs, weight, dyno results, and what you want out of your car and I'm sure they can help you pick the right converter.
