Well, we are going to do this stuff around 4:30 tonight, but if it doesn't fix the problem I might have you take a look one of these days. If you want some beers your welcome to stop by and hang out while I do work.
I scanned the GTP last night after they changed plugs, wires, and fixed the vac leak. It was running decent for a stock pulley 97 with alot of miles on a DHP 1.0 file. Idle was off, cruise and part throttle were a tad lean but not bad at all. WOT trims locked in at +8 with 960 O2's according to narrow-band. 18 deg of timing at WOT, not even a blip of KR.
Should be the rockers, possibly front ported manifold. LIM is ported, too but the SC isn't... Just was saying that it. Wasn't a true factory freak..anymore at least.
I've been Crazy busy, still trying to figure the best way to get the suburban to you for a full day. The Camaro and I have been in a few times for washing, though. It will need sealant before winter sets in, too.
Yeah, paceshitters, I was asking $200 so... idk... They're setup right now to hook right up to the stock exhaust so you shouldn't have to modify them. I also might have a gasket from the stock/paceshitters connection laying around too. They don't have a cat on them FYI, you'll have to run them catless or cut out the current one and transfer. Tis up to you, but i just want you to know, must disclose all info
You might remember, but just in case you don't, there is a W-body weld in 3" DP on there, that goes into 3" cat and piping. The flange at the manifold is stock size though.
