Here’s the deal. My car came with a Granatelli (sp?) MAF when I bought it. I’ve heard of a lot of people having fuel mixture problems and losing power with the aftermarket MAFs. I’ve also heard that tuning LS1s with aftermarket MAFs can be a bitch. The car doesn’t feel sluggish, although I’ve only driven it less than 5 miles since I’ve bought it. What would you guys say I should do? -Keep the aftermarket MAF and see if everything seems in check when I get it tuned in the spring. -Try to get someone on LS1Tech to trade me their stock MAF for my aftermarket one. Any help and input from the LS1 guys would be appreciated…thanks guys ---

Yeah…I knew the aftermarket MAF was just going to lead to headaches down the road. The tough part’s going to be suckering someone into trading me their nice OEM one for my aftermarket. If that doesn’t happen, it looks like I’ll be taking a trip to the stealership. ---
