Engine Hesitation driving upon start up
Upon a cold start I typically roll back out of the garage wait for 30 seconds and take off. I notice if I do light rev's when the engine is cold between 2-3k rpm I get popping noises and upon the initial drive off the car is sluggish and sometimes jerky. I recently updated to a stage 2 BPM tune and this is when I started noticing the behavior I am experiencing. Any feed back is welcome.
Thanks

Usually any car is jerky until everything is up to normal operating temps, engine, tires etc. Especially high performance cars. I always let the engine warm up a couple minutes before I take off. My Supra I let it warm up to ten minutes sometimes. Proper engine warmup and cool down is always a good idea!

I figured it has something to do with the added performance mods because the car works like a dream once to normal operating temps. I try to never go past 3k rpm until then but I noticed it once I deleted my cats and upgraded to a stage 2 tune so had to ask, thanks
