swapped intakes from an ls3 with a fast 90 to a fast 102 with a nw 102 tb and now have major idle issues. The engine is a drive by cable 408 with ported ls3 heads. Idle was great before with the ls3 intake and fast 90mm tb. Now with the 102 set up it sux. It has a lot of surge to it now. I haven't even tried to drive the car yet. There was also an issue with the tps voltage being high as well. I ended up slotting the mounting holes for the tps sensor just so I could crack the tb open some. I have tried adding base idle air also which doesn't seem to help. I have done every thing but drill a hole in the tb blade which I was hoping not to have to do. I have also noticed at idle the tps keeps going to 1-2%. I will add a scan log along with the tune and configuration. Whats the secret to tuning a damn 102 intake? This thing is kicking my ass. I didn't have any trouble dialing in the idle with the ls3 intake and fast 90. I know I will need to retune the VE and maf for the 102 but I wanted to try to dial in the idle first.
Do you pretty much have to drill a hole in the blade on the 102 tb?
